Question
A rectangular piece of land has a perimeter of 88 metres
and length of 20 metres. If the area of the land is to be divided into 6 equal portions, then what will be the area (in m2) of each portionSolution
Let the breadth of the land = ‘b’ metres Then, perimeter of the land = 2 × (20 + b) Or, 2 × (20 + b) = 88 Or, 40 + 2b = 88 Or, 2b = 88 – 40 = 48 So, b = 48/2 = 24 And so, total area of the land = 20 × 24 = 480 m2 So, area of each of the 6 equal portions = 480 ÷ 6 = 80 m2
