Question

a square law has 2 metre wide path surrounding it the area of the path is 136 metre square find area of lawn
​

Answer 1

Answer:

x = 120/ 8 = 15

Side of the lawn = 15 m Hence, Area of the lawn = (Side)² = (15 m)² = 225 m²

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

Length PQ = (x m + 2 m + 2 m) = (x + 4) m

Area of PQRS = (x + 4)² = (x² + 8x + 16) m²

Now, Area of the path = Area of PQRS – Area of the square lawn

136 = x² + 8x + 16 – x²

136 = 8x + 16

136 – 16 = 8x

120 = 8x

x = 120/ 8 = 15

Side of the lawn = 15 m Hence, Area of the lawn = (Side)² = (15 m)² = 225 m²
