Question
A rectangular piece of land has a perimeter of 56 metres
and length of 22 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 × (22 + b) Or, 2 × (22 + b) = 56 Or, 44 + 2b = 56 Or, 2b = 56 – 44 = 12 So, b = 12/2 = 6 And so, total area of the land = 22 × 6 = 132 m2 So, area of each of the 6 equal portions = 132 ÷ 6 = 22 m2
