Question

The area of a rectangular lawn is 255m2. If its length is 15m , find its perimeter.

​

Answer 1

Answer:

Perimeter is 124

Step-by-step explanation:

Area of rectangle= l×b

255= 15×b

b= 17m

=> Perimeter = 2(l+b)

2(15+17)

2×32 = 124m

Answer 2

Answer:

64m

Step-by-step explanation:

area of rectangle - l*b=225m2

15*b=225m2

b=225/15=17m.

i.e, breath of rectangular lawn=17m.

perimeter=2(l+b)

2(15+17)=64m.
