Question

Find the perimeter and area of the following combined figure.​

Answer 1

Area =867.9 cm2

Perimeter =99.4 cm

Explanation:

Perimeter:

`p=28+20+\pi r`

`\pi r=\pi (10)=10\pi`

`p=28+20(2)+10\pi =68+10\pi =99.4 cm`

Area:

`A=(28)(20)+(\pi (14)^(2) )/(2) =560+307.87=867.9cm^(2)`

Hope this helps

Answer 2

perimeter =136cm

and

area =560+308= 868 sq.cm
