The length of a square is p inches. the width of a rectangle is also p inches. the perimeter of a rectangle is 10 inches more than the perimeter of the square. the rectangle has a perimeter of b inches. write an equation relating p and b.

10+4p=b

Step-by-step explanation:

The length of the square is p and the width is p so the perimeter (adding all 4 sides) is p+p+p+p = 4p.

The perimeter of the rectangle is 10 more than the square. So for it p = 10+4p.

The perimeter of the rectangle is also equal to adding all 4 sides which is b inches.

So 10+4p=b.

a. is correct
