Laura’s yard is in the shape of a square and a half-circle. She just got a puppy named Sprinkles for her birthday. In order to keep him safe, she wants to line the perimeter of her yard with a fence. -can someone answer (C) and (B)

4L + πr

Step-by-step explanation:

Since her yard is a square and half a circle, and she wants to fence the whole distance around the square and the half circle, then she needs to know the perimeter of a square and semicircle.

The perimeter of a square which is the distance around the square is given by 4L where L is the side length.

The perimeter of a circle, which is the circumference of a circle is 2πr, where r is the radius of the circle Therefore, half a circle would be 2πr/2 = πr

27 +27 or 27times 2=54

the diffrence is 0

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
