Question

Find the area of a figure

Answer 1

4.62 sq ft

Explanation:

Area of rectangle = 2.5 x 1 = 2.5

To get area of triangle we must use the altitude theorem to find the height:

let 'x' = altitude (or height)

x/1.5 = 2/x

cross-multiply to get:

x² = 3

x =
`√(3)`

Area of triangle = 1/2(2.5)(
`√(3)`)

= 1.25
`√(3)` which is approx 2.12

Total area = 2.5 + 2.12 = 4.62
