Round each measurement to the nearest ten. Then estimate the area of the rectangle.
The rectangle shows one side is 86 inches and another side is 42 inches.
Rounding each measurement to the nearest ten, the rectangle becomes 90 inches by 40 inches.
To estimate the area of the rectangle, we multiply the length by the width. Therefore, the estimated area is 90 inches * 40 inches = 3600 square inches.
