Question

The area of a rectangular field is 768 M2 and its length is 32 m . Find (I) its breadth (II) The cost of fencing it at Rupees 32 per metre.​

Answer 1

I)area of field=length×breadth

768=32×b

768/32=b

b=24 m

ii)cost of fencing per meter=32rs

cost of fencing for 768m=768×32

=

24576rs

hope it helps you

Answer 2

area = 768 m2

length = 32 m

let the breadth be x

area of rectangle = l × b

768m2 = 32 × x

x = 768/32

x = 24

So, the breadth is 24m

perimeter of field = 2(l+b)

=2(32 + 24)

=(2×32) + (2×24)

= 64 + 48

= 112m

cost of fencing = perimeter of field × cost of fencing in a meter

= 112 × 32

total cost of fencing = Rs-3584
