Question

Find the area of the irregular figure

Answer 1

Rectangle=21 times 14=294 cm^2
Triangle=Base Times Height
Height=21-12=9cm
Area of triangle=16 times 9 =144

Area of both=294+144=438cm^2

Answer 2

The area of the irregular figure is
`366\ cm^(2)`

Explanation:

we know that

The area of the irregular figure is equal to the area of rectangle plus the area of triangle

The area of rectangle is equal to

`A=14*21=294\ cm^(2)`

The area of triangle is equal to

`A=(1)/(2)(16)(21-12)=72\ cm^(2)`

Sum the areas

`294\ cm^(2)+72\ cm^(2)=366\ cm^(2)`
