Step-by-step explanation:
Given area of square field = 625m ^2
Let a be side of field
then a^2=625m
[a=25m]
The length of the wire required to fence 4 rounds of the square garden = 400 m
Given :
The area of the square garden is 625 sq.m
To find :
The length of the wire required to fence 4 rounds of the square garden
Solution :
Step 1 of 2 :
Calculate length of the side of the square garden
Let length of the side of the square garden = x metre
∴ Area of the square garden = x² sq.m
x² = 625
⇒ x² = 25²
⇒ x = 25
So length of the side of the square garden = 25 metre
Step 2 of 2 :
Calculate length of the wire required to fence 4 rounds of the square garden
Perimeter of the square garden
= 4 × Length of the side of the square garden
= 4 × 25 metre
= 100 metre
∴ Length of the wire required to fence 1 round of the square garden = 100 metre
Hence length of the wire required to fence 4 rounds of the square garden
= 4 × 100 metre
= 400 metre
