Question

the area of a rectangular field is 3456 metre square and its width is 36 find the cost of fencing the field at the rate of rupees 3.50 per metre​

Answer 1

Answer:

first we find the length of rectangul

Area=breadth × length

3456= 36×lenth

3456/36= length

96m = length

then, we find the perimeter of this rectangle

2(l+b)= perimeter

2(96+36)= perimeter

192+72 = perimeter

264 = perimeter

cost of fence

3.50×264

=924Rs

Answer 2

Answer:

Area=3456. Width=36m

l*b=3456

L*36=3456

L=3456/36

L=96m

Perimeter=2l+2b

=2*96+2*36

=192+72

=264m

Cost of fensing=264*3.59

=947.76 rupers
