A triangle has an area of 80 yd^2 and a height of 10 yd. How long is the base of a triangle? Enter in the answer in the box.

sdas [7]

Answer:

Length of the base is 16 yards.

Step-by-step explanation:

We are given that,

Area of the triangle = 80 yd²

Height of the triangle = 10 yards

Since, we know,

Area of a triangle = $\frac{1}{2}\times Base \times Height$

So, we get,

$80=\frac{1}{2}\times Base \times 10$

i.e. $80=Base \times 5$

i.e. $Base=\frac{80}{5}$

i.e. Base = 16 yards

Thus, the length of the base is 16 yards.
