Jessie has a piece of cardboard that is 8.5 inches by 11 inches. Sh makes a picture frame with the cardboard by cutting out a 4 inch by 4 inch square from the center of the cardboard. What is the area of the frame?

First, we determine the area of the piece of cardboard by multiplying its dimensions.
area of cardboard = (8.5 inches) x (11 inches) = 93.5 in²
Then, we solve for the area of the cut out square,
area of the square = (4 inches) x (4 inches) = 16 in²
Then, we subtract the areas giving us the area of the frame which is equal to,
77.5 in²

Given Data

Dimension of cardboard

Length =8.5 inches

Height = 11 inches

Area of cardboard

= Length * Height

= 8.5*11

= 93.5 square inches

Dimension of cut out square

Length = 4 inches

Height = 4 inches

Area of cut out square

= Length * Height

= 4*4

= 16 square inches

Hence the area of the frame is

= Area of cardboard - Area of cut out square

= 93.5 - 16

= 77.5 square inches
