A rectangle mural has a shorter side of 5 yards. The longer side measures 3 yards longer. How many square yards in the mural's area?
The longer side of the mural is 5 + 3 = 8 yards.
The area of a rectangle is calculated by multiplying the length by the width. In this case, the length is 8 yards and the width is 5 yards.
Area = length x width
Area = 8 yards x 5 yards
Area = 40 square yards
Therefore, the mural's area is 40 square yards.
