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

Answer:

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

Step-by-step explanation:

we know that

The area of a triangle is equal to

$A=\frac{1}{2}bh$

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

$80=\frac{1}{2}b(10)$

$80=5b$

$b=80/5=16\ yd$

Answer 2

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