Question

Work out the area of this shape

Answer 1

75.5

Explanation:

First, the picture is not to scale.

The Area of the bottom (2) rectangle is 33

base x height = A

11 x 3 = 33 (where did I get 3? Total height of shape is 8. Trapezoid is 5)

(8-5 = 3)

Area of the trapezoid:

A =
`(h (B_(1) + B_(2)) )/(2)`

=
`((5)(6 + 11))/(2)`

=
`(5(17))/(2)`

=
`(85)/(2)`

= 42.5

42.5 + 33 = 75.5
