Question

A triangle has an area of 369.25 square inches. The height of the triangle is 42.2 inches. What is the length of the base of the triangle?

Answer 1

Explanation:

`1 / 2 * base * height = area`

`1 / 2 * x * 42.2 = \ 369.25 \`

`x = 369.25 / 21.1`

`= 17.5`

Answer 2

Base = 17.5 inches.

Explanation:

Given : A triangle has an area of 369.25 square inches. The height of the triangle is 42.2 inches.

To find : What is the length of the base of the triangle.

Solution : We have given

Area of triangle = 369.25 square inches.

Height = 42.2 inches.

Area of triangle =
`(1)/(2)*base*height`.

Plugging the values.

369.25 =
`(1)/(2)*base*42.2`.

On multiplying both sides by 2

369.25 * 2 = base * 42.2

738.5 = base * 42.2

On dividing both sides by 42.2

Base = 17.5 inches.

Therefore, Base = 17.5 inches.
