Jim wants to build a toy house. He plans for the width to be 2 feet and the length to be 3 feet. Then he decides to add to the length. The amount he wants to add to the length is shown by the variable y .

Respuesta :

lets w width, l length, y amount add, A area, P perimeter


A=lw=(3+y)(2)=6+2y ft²

p= 2l+2w= 2(3+y)+2(2)= 6+2y+4 =10+2y
