Question

If the length of a rectangle is g inches and the width is h inches:

Write two equivalent expressions to represent the perimeter of the rectangle.



If the width is 4. 7 in, and the perimeter is 68. 4in, calculate the length of the rectangle.

Answer 1

Perimeter: h + h + g +g = P or 2h + 2g = P

P = 2h + 2g

68.4 = 2(4.7) + 2g

68.4 = 9.4 + 2g

59 = 2g

g = 29.5

Length: 29.5 inches
