Question

A length of a rectangular garden is 110m and it's breath is 90m . find the length of wire needed to fence the garden three times​

Answer 1

perimeter of rectangle = 2(l+b)

= 3×perimeter

= 3×2(l+b)

= 3×2(110+90)

= 3×2(200)

= 6×200

= 1200m

Hence,1200m of wire is required .

Answer 2

perimeter = 2*(l + b)

= 2*(110+90)

= 2*200

= 400m

length of wire needed = 3*400

= 1200m
