Question

Find the perimiter of this shape

Answer 1

The perimeter of the shape is (7x²+10x+81) inches.

Explanation:

When finding the perimeter of a shape, you have to add up all the side lengths :

`p = 31 + (4 {x}^(2) + 8x) + (3 {x}^(2) - 5x + 20) + (7x + 30)`

`p = 31 + 4 {x}^(2) + 8x + 3 {x}^(2) - 5x + 20 + 7x + 30`

`p =( 7 {x}^(2) + 10x + 81) \: inches`
