Question

A triangle has an area of 80 yd22 and a height of 10 yd How long is the base of the triangle? Enter your answer in the box.

Answer 1

Area = 80 sq yards
height = 10 yards
80 = .5* 10 * base
base = 16

Answer 2

The base of triangle is equal to
`16\ yd`

Explanation:

we know that

The area of a triangle is equal to

`A=(1)/(2)bh`

where

b is the base of triangle

h is the height of triangle

In this problem we have

`A=80\ yd^(2)`

`h=10\ yd`

substitute in the formula and solve for b

`80=(1)/(2)b(10)`

`80=5b`

`b=80/5=16\ yd`
