Question
A rectangular piece of land has a perimeter of 66 metres
and length of 18 metres. If the area of the land is to be divided into 9 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 × (18 + b) Or, 2 × (18 + b) = 66 Or, 36 + 2b = 66 Or, 2b = 66 – 36 = 30 So, b = 30/2 = 15 And so, total area of the land = 18 × 15 = 270 m2 So, area of each of the 9 equal portions = 270 ÷ 9 = 30 m2
