Question

(Please help asap!) The shape is composed of squares and quarter circles. Select all the expressions that represent its perimeter

Answer 1

`a - \: \: 42 + 14\pi`

Explanation:

There are 6 sides that are 7 in length.

`7 * 6 = 42`

There are 4 quater circles which equals the perimeter of one circle

`circles \: perimeter - 2\pi \: r`

`2\pi \: r = 2 *\pi * 7`

`= 14\pi`

therefore final expression is

`= 42 + 14\pi`
