Question

Drew is finding the base of a triangle that is 20 m in height and it's area is 100 meters squared he says the base is 5 meters is he correct why or why not​

Answer 1

He is not correct, beacuse the base is 10m

Explanation:

To solve this problem we have to use the formula to calculate the area of ​​a triangle and to clear the base

a = area = 100 m²

b = base

h = height = 20m

a = (b * h) /2

we solve b

(2 * a) /h = b

we replace the known values

b = (2 * 100m²) / 20m

b = 200m² / 20m

b = 10m

As we can see he is not correct, since the base is 10m
