Question

A field is 90 m long and 78 m broad. A path 3.5 m wide is to be built outside the field. Find the area of the path and also find the cost of gravelling on it at the rate of ₹ 1.40 per m².​

Answer 1

Answer:

Length of field = 90m

Breadth of field = 78m

Area without path = 90×78 m²

=7020m²

Length along with path = 90+3.5+3.5 = 97m

Breadth along with path = 78+3.5+3.5= 85m

Area = 97×85 m²

=8245m²

Area of path = 8245m² - 7020m² = 1225m²

Cost of colouring = 1225×1.40

=Rs 1715
