Question

Finding area ?

How did they get a=90 in sq

Answer 1

90 sq in

Explanation:

The total area in the figure can be divided into two areas.

The
`area_(rectangle)` is the area of the
`8* 10` rectangle.

The
`area_(triangle)` is the area of the adjacent triangle to the rectangle.

`area_(rectangle)=length* breath=10* 8=80`

`area_(triangle)=(1)/(2)* base * height=(1)/(2)* 4* 5=10`

Total area=
`area_(rectangle)+area_(triangle)=`90
