a land area was divided among three heirs in the ratio 5:2:4 . if the largest share was 20 hectares of the land .what is the total area of the land

with solution please and what type of proportion thank you very much
​

Answer:

44 hectares

Step-by-step explanation:

The largest number in the ratio is 5 and corresponds to the largest share.

The largest share is 20 hectares.

20/5 = 4

Multiply each number in the ratio by 4 to get the number of hectares of that portion.

5 * 4 = 20

2 * 4 = 8

4 * 4 = 16

20 + 8 + 16 = 44

Answer: 44 hectares

If you need to show a proportion, then do it this way.

The ratio is 5:2:4

Add 5 + 2 + 4 = 11

The ratio of the largest portion to the total area is

5/11

The largest portion is 20 hectares, and the total area is unknown, so we use x. The ratio of the largest portion to the total area is

20/x

We set the two ratios equal creating a proportion.

5/11 = 20/x

Cross multiply

5x = 11 * 20

Divide both sides by 5

x = 11 * 4

x = 44

Answer: 44 hectares

The measures of two angles of a triangle are given. Find the measure of the third angle.
147° 12′, 30° 19′
51° 20′ 14″, 106° 10′ 12″

Example: Applying the Angle Sum of a Triangle Property
The measures of two of the angles of a triangle are 48° and 61°. See Figure 17.
Find the measure of the third angle, x.
SOLUTION 48° + 61° + x = 180° The sum of the angles is 180°.
109° + x = 180° Add.
x = 71° Subtract 109°.
The third angle of the triangle measures 71°.

The Riemann sum, the limit as the maximum of delta x sub i goes to infinity of the summation from i equals 1 to n of f of the quantity x star sub i times delta x sub i , is equivalent to the limit as n goes to infinity of the summation from i equals 1 to n of f of the quantity a plus i times delta x, times delta x with delta x equals the quotient of the quantity b minus a and n. Write the integral that produces the same value as the limit as n goes to infinity of the summation from i equals 1 to n of the product of the quantity 2 plus 3 times i over n and 3 over n.

f(x) = 350(1.68)x
