Question

A rectangular field 150 m long and 100 m wide has a 10 m wise path around it find the area of the path the cost od levelling it at rs 3.50 per square m

Answer 1

Hey there!

Answer:

Area of path = 4600 m^2

Cost of levelling  = Rs. 16100

Step-by-step explanation:

Length of rectangular field = 150 m

Breadth of rectangular field = 100 m

Area of rectangular field ABCD = length * breadth

                                                     = 150 * 100

                                                     = 15000 m^2

Length of rectangle EFGH = 150 - (10 + 10)  = 130 m

Breadth of rectangle EFGH = 100 - (10+10)  = 80 m

Area of rectangle EFGH = Length * Breadth

                                        = 130 * 80 = 10400 m^2

Area of path = area of rect. ABCD - area of rect. EFGH

                    = 15000 - 10400 m^2

                    = 4600 m^2

Now, Cost of levelling it 1 m^2 = Rs. 3.50

Cost of levelling it 4600 m^2 = 4600 * 3.50 = Rs. 16100
