a rectangular painting including the frame is 28 inches wide and 24 inches tall.the opening inside the frame is 24 inches wide and 20 inches tall.what is the area covered by the frame
192?
To calculate the area covered by the frame, we need to find the difference between the area of the outer rectangle (including the frame) and the area of the inner rectangle (the opening inside the frame).
Area of the outer rectangle = width × height
Area of the inner rectangle = width × height
Given:
Width of the outer rectangle = 28 inches
Height of the outer rectangle = 24 inches
Width of the inner rectangle = 24 inches
Height of the inner rectangle = 20 inches
Area of the outer rectangle = 28 inches × 24 inches = 672 square inches
Area of the inner rectangle = 24 inches × 20 inches = 480 square inches
Area covered by the frame = Area of the outer rectangle - Area of the inner rectangle
= 672 square inches - 480 square inches
= 192 square inches
Therefore, the area covered by the frame is 192 square inches.
subtract the smaller rectangle from the larger. The remainder is the area covered by the frame.
28*24 - 24*20 = ?
or, rewriting things a bit,
28*24 - 20*24 = 8*24 = ?
