Question

A triangular window has an area 240 square feet and height 16 feet. What is its base?

Answer 1

30 feet

Explanation:

Area of a triangle = bh/2

A = bh/2

240 = b(16)/2

480 = (16)b

30 = b

Base = 30 feet

I hope this helps!

Answer 2

30 ft

Explanation:

Formula to find the area of a triangle is :

Area =
`(1)/(2)` × base × height

Given that,

Area of the triangle = 240 ft²

Height = 16 ft

Base = ??

Let us find now.

Area =
`(1)/(2)` × base × height

240 = =
`(1)/(2)` × b × 16

240 × 2 = 16b

480 = 16b

Divide both sides by 16.

30 ft ⇒ base
