Question
Length of a rectangle is equal to the side of a square.
If area of the square and rectangle is 441 m2 and 294 m2, respectively then find the perimeter of the rectangle.Solution
Side of square = √441 = 21 metres Area of rectangle = 294 m2 Breadth × 21 = 294 Or, Breadth of the rectangle = 14 metres Perimeter of the rectangle = 2 × (14 + 21) = 70 metres
