The length of a rectangle is (x+3) inches long, and the width is 5 inches. If the area is 60 square inches, write and solve an equation.

Question

Find the length of the rectangle.

Answer 1

area of rectangle = length * width

 

5*(x + 3) = 60

 

5x + 15 = 60

 

5x = 60 - 15

 

5x = 45

 

x = 45/5 = 9 inches

 

Therefore length = 12 cm and width = 5 cm
