#### Answer

a) 24 inches
b) 32 inches

#### Work Step by Step

a) The picture is 5 inches long by 7 inches wide. The equation for the perimeter of a rectangle is l + l + w + w. To find the perimeter, add 5 + 5 + 7 + 7 = 24 inches.
b) The one-inch frame will add an extra two inches to the length and the width, as it will border the 5x7 picture on either side. This means the dimensions of the frame are 7 x 9, where the length is 7 and the width is 9. To find the perimeter, apply the perimeter equation of l + l + w + w:
7 + 7 + 9 + 9 = 32 inches.
