First we must find the length and width of the rectangle. If the perimeter = 56, then: 56m = Length + Width + Length + Width We know the length to be 8m: 56 = 8+ 8 + 2(WIdth) 56 -16 =2(Width) 40 = 2(Width) Width = 20m Then, to calculate the area of a rectangle we multiply: length x width = 8m x 20m = 160m² The units of area are the units of length squared since we are multiplying two units of length (e.g. m • m).
