Question

find the coast of tiling a field 32 m long and 20m wide at rupees 4.75 per square meters. Also find the cost of fencing it at 75 paise per meters.

Answer 1

cost of tiling the field = area of field* rupees per square meter
total cost= 640*4.75= 3040.00
cost of fencing it will be = perimeter * rupees per meter
total cost= 2(32+20)*0.75= 104*0.75= 78.00 rupees

Answer 2

First find area

A=l×b

=32×20=640 sq. M

Cost = 4.75 per sq m×640 sq m

=rs 3040(ans)

Second part of fencing

Find perimeter

P=2(l+b)

=2(32+20)

=2(52)

104 metres

Cost of fencing =0.75 ruppes×104

=rs 78 (ans)
