Question

a square lawn has a 2 m wide path surrounding it. if the area of the path is 136 metres square, find the area of the lawn​

Answer 1

Step-by-step explanation:

Let ABCD be the square lawn and PQRS be the outer boundary of the square path.Let the side of the lawn AB be x m.Area of the square lawn = x²

Let ABCD be the square lawn and PQRS be the outer boundary of the square path.Let the side of the lawn AB be x m.Area of the square lawn = x²Length PQ = (x m + 2 m + 2 m) = (x + 4) mArea of PQRS = (x + 4)² = (x² + 8x + 16) m²Now, Area of the path = Area of PQRS – Area of the square lawn136 = x² + 8x + 16 – x²136 = 8x + 16136 – 16 = 8x120 = 8xx = 120/ 8 = 15Side of the lawn = 15 m Hence, Area of the lawn = (Side)² = (15 m)² = 225 m²
