Question

A rectangular plot of land is 40m long. The cost of leveling the plot at the rate of RS 8 per my is RS 8320. Find (i) the breadth of the plot. (ii) the cost of fencing the plot at the rate of RS 27.5 per meter.

Answer 1

i hope it will help

Answer 2

Hey friend!

=>To find breadth first we need the area so the cost of area per metre square is 8 and total cost is 8320. So the area will be 8320/8
=8320/8
=1040

The area is 1040m square
Area=length *breadth
1040=40*breadth
1040/40=breadth
26=breadth
The breadth is 26m

Fencing means making a compound wall type so we have to find perimeter.

Perimeter = 2(length + breadth)
=2(40+26)
=2(66)
=132

So cost will be 132*27.5
=3630/-
