Question

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.​

Answer 1

The base length of triangle = 16 yd

Explanation:

Formula:-

Area of triangle

area A = bh/2

b - base of triangle

h - height of triangle

To find the area of triangle

It is given that,A triangle has an area of 80 yd^2 and a height of 10 yd.

here, b = ?, A = 80 yd^2 and h = 10 yd

A = bh/2

80 = (b*10)/2

5b = 80

b = 80/5 = 16

Therefore the base length of triangle = 16 yd

Answer 2

Length of the base is 16 yards.

Explanation:

We are given that,

Area of the triangle = 80 yd²

Height of the triangle = 10 yards

Since, we know,

Area of a triangle =
`(1)/(2)* Base * Height`

So, we get,

`80=(1)/(2)* Base * 10`

i.e.
`80=Base * 5`

i.e.
`Base=(80)/(5)`

i.e. Base = 16 yards

Thus, the length of the base is 16 yards.
