Question

The cost of fencing a square garden is at rs 400 at the rate of rs 1 per meter.Find the area of garden

Answer 1

perimeter of square = cost of fencing / rate of fencing
perimeter = 400/1 = 400 m
perimeter = 4 * side
400 = 4 * side
side = 400/4 = 100 m
area = 100*100= 10000 m^2

Answer 2

perimeter of square =cost of fencing/ rate of fencing

perimeter =400/1

=400m

400=4×side

side=400/4

=100m

area =side ×side

100×100
