Question

A rectangular field measuring 75 m by 60m has a
1.5 m wide path running around outside it. Find the
cost of gravelling this path at the rate of 78 per sq. m. 3​

Answer 1

Step-by-step explanation:

Given:

Length of the plot = 125 m

Breadth of the plot = 78 m

Area of plot ABCD=Length×Breadth

=125×78

=9750m

2

Length of the plot including the path =(125+3+3)m=131m

Breadth of the plot including the path =(78+3+3)m=84m

Now,

Area of plot PQRS including the path =Length×Breadth

=(131×84)

=11004m

2

Area of path = Area of plot PQRS − Area of plot ABCD

=110049750

=1254m

2

Cost of gravelling =RS75 per m

2

Cost of gravelling the whole path =RS(1254×75)=RS94050

Hence, cost of gravelling the path is RS 94050.
