Best answer

Given length of rectangular park is 14m more than its breadth.

Let the breadth be b m .

∴ Length of the park will be l = b + 14 m

Given perimeter = 200 m

2 × (l + b) = 200 m

2 × (b + 14 + b) = 200 m [∵ l = b + 14]

2 × (2b + 14) = 200 m

2b + 14 = 200/2 m

2b + 14 = 100 m

2b = 100 – 14 m

2b = 86 m

b = 86/2 m

b = 43 m

Length Length of the park = 57 m

Area of a rectangle = (length × breadth) unit2

= (57 × 43) m2 = 2,451 m2

Area of the park = 2,451 m2
