Question

How do I solve this?

Answer 1

100 ft²

Explanation:

The area (A) of the triangle is calculated as

A =
`(1)/(2)` bh ( b is the base and h the perpendicular height )

Here b = 25 ( parallel to the base of the rectangle ) and h = 8, then

A =
`(1)/(2)` × 25 × 8 = 12.5 × 8 = 100 ft²

Answer 2

Explanation:

Base = 25 ft

height = 8 ft

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

`= (1)/(2)*25 *8\\\\= 25 * 4\\\\= 100 ft^(2)`
