Question

solve these problem........,,,​

Answer 1

length of wire = 480m

then

perimeter of square = 4a

4a= 480

a = 120

three round = 120÷3

a = 40

perimeter of pond = 4a

then 4×40 = 160

length of pond = 40

Answer 2

Let one measurement of one side of the garden is a.

So according to the question,a^2=154

a=12.4 cm.

Therefore total wire required to fence one round of the garden is =4a=49.6.

So total wire required for 4 rounds is=4×49.6=198.4 cm
