how do you determine height of a triangle

Question

A square and triangle have equal areas. If a side of he square is 10" and the base of the triangle is 10" ..how do you determine the height of the triangle ?

Answer 1

The side of the square is 10 inches.

The area of the square is thus
= side * side
= 10 * 10
= 100 inches^2

The square and triangle have the same area, so the area of the triangle is also 100 inches^2.

The formula for the area of a triangle is 1/2 * base * height.

Since the base of the triangle is 10 inches and its area is 100 inches^2, we have:

100 = 1/2 * 10 * height
100 = 5 * height
height = 100 / 5
height = 20 inches

Hence, the height of the triangle is 20 inches.
