WIDTH IS 5 INCHES PERIMETER IS 34 INCHES WHAT IS THE RECTANGLE

Question

The perimeter of a rectangle equals the sum of the lengths of its four sides. If the width of a rectangle is 5 inches and its perimeter is 34 inches, find the length of the rectangle.

Answer 1

Perimeter of rectangle = 2(l+b)

Width = 5inches

Perimeter = 34inches

then 34 = 2(l+5)

34 = 2l+10

Subtract 10 from each side.

34-10 = 2l+10-10

24 = 2l

Divide by 2 to each side.

24/2 = 2l/2

12 = l

length of given rectangle = 12inches
