The length of a rectangle is 5 inches greater than the width

Question

a. write a variable for the width of rectangle

b. write an expression for the length of the rectangle

c. write a simplified expression for the area of the rectangle(area=length x width)

d. Find the area of the rectangle when the width is 3 inches

e. find the area of the rectangle when the length is 9 inches.

Answer 1

Parts A and B:

L = w+5 ---> w = L-5

Part C: Area = Length * width

A = (w+5)*w = w(w+5)

Part D: w=3 ---> L=8 ---> Area = 24

Part E: L=9 ---> w = 9-5=4 --> Area = 36
