Question

I need help the question is what is the are of the composite figure

Answer 1

Option 4

Explanation:

Area of a trapezoid =
`(1)/(2)(b_1+b_2)h`

Here,
`b_1` and
`b_2` are the bases and 'h' is the height between the bases.

Area of the composite figure = Area of two trapezoids given

=
`(1)/(2)(12+12)14+(1)/(2)(25+31)11`

=
`(1)/(2)(24)(14)+(1)/(2)(56)(11)`

= 168 + 308

= 476 square ft

Option 4 is the answer.
