Question

The area of a playground is 400sq m.If its length is 25 m,how much wire will be required to fence it ?​

Answer 1

Answer:

Area of Rectangular Park : 400

area of Rectangle = length× breadth

length = 25m

breadth = x

25 × x = 400

x = 400 ÷ 25 = 16 m

fencing = perimeter of park

perimeter of Rectangle = 2(l+b)

perimeter of park = 2(16+25) = 82m

82m wire will be needed

Answer 2

Answer:

82 meters

Step-by-step explanation:

area of ground=l×b

400 sq m=25m×b

b=400/25m

b=16m

perimeter of rectangle=2(l+b)

perimeter=2(25+16)

=2(41)=82meters

Therefore, required wire for fencing=82 meters
