Answer:
The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h. Hence, to find the area of a tri-sided polygon, we have to know the base (b) and height (h) of it. It is applicable to all types of triangles, whether it is scalene, isosceles or equilateral. To be noted, the base and height of the triangle are perpendicular to each other. The unit of area is measured in square units (m2, cm2).

Since the question is incomplete, answer will be subjective. An example of Evaluating Expressions is find h + 8 − 9 j − h; where h = 7 and j = 5.
What is the Evaluating Expressions?The evaluating expressions is known to be a form of digital and printable board work that can help students in working on substituting values in terms of variables of an algebraic expression.
Evaluating the Expression below:
h + 8 − 9 j − h;
Therefore, where h = 7 and j = 5
7+ 8 − 9 (5) − 7.
SO: 7 + 8 - 45 -7
= -37
Therefore the answer to the Evaluating Expression is -37.

find the areas of the trapezoids
Answer:
A = 7.5in^2
Step-by-step explanation:
Your a (base) is 4, which is A-P.
Your b (base) is 1, which is T-R.
Your h (height) is 3, which is the distance from the bottom of the trapezoid to the top.
Then you plug it into your formula, A = (a + b) x h/2 (A = (4 + 1) x 3/2)
That equals 7.5.
Jacob is building a square pyramid for a class project. He needs to cover the entire pyramid in aluminum foil. The base of the pyramid has a perimeter of 76 centimeters. The slant height of each triangular side is 28 centimeters. What is the surface area, in square centimeters, of Jacob's pyramid?
Answer:
The surface area of Jacob's pyramid is 1425cm²Step-by-step explanation:
Step 1
Find the dimensions
We will be finding the dimensions to find the surface area. We know on what is the perimeter of the square base, and what is the slant height of each triangle. So that's enough to know, if we know the perimeter, of the square base, we can divide that by 4 to get our 1 side's length. Then, we can calculate the square base's SA and the Triangle's SA!
76/4=19
Now we have our dimensions ready!
Square Base each side length: 19 centimeters
Triangle slant height for each single: 28 centimeters
Step 2
Figure out the SA's now!
Now, let's figure out all the SA's.
First the square base!
19x19=361cm²
Now, let's figure out the SA for all of the triangles
As we know, to find the Area or Surface Area (SA) of each triangle, we have to use this formula:
[tex]SA=\frac{1}{2} *B*H[/tex]
But to find the surface area of 4 triangles at once, we will have to use this formula:
[tex]SA=2*B*H[/tex]
Let's do it now!
[tex]SA=2*19*28\\=2*532\\=1064[/tex]
1064cm²
Step 3
Add all the SA's up to get FINAL ANSWER!
Easy peasy lemon squeasy! Let's get on it people!
361+1064=1425cm²
The surface area of Jacob's pyramid is 1425cm²

Really easy the best one will get brainly!
Answer:
the answer for the parrallelogram should be 48 cm^2 because you multiply 8 times 6 making the answer 48.
The answer for the triangle for the area should be 12 because the formula for finding the area of the triangle is 0.5 times base times height.
the answer for the missing dimension of the triangle should be 10 making the answer 10.
the answer for the area of the triangle should be 6 because you multiply 0.5 or 1/2 times 4 times 3 making the answer to be 6.
the answer for the last one should be 90 because you do as i did multiplying 0.5 or 1/2 times 9 times 20 making the answer to be 90.
