Question

Two cross roads 2.5 m wide have been constructed in the middle of a garden

crossing each other at right angles, running parallel to the sides of the garden 35 m

long and 20 m wide. Find the cost of constructing the roads at the rate of ₹ 100 per

sq.m.​

Answer 1

Answer:

width = 5 m

length of first parallel road 70 m

area of first road 70 × 5 = 350 sq.m

length of second road 45 m

area of second road = 45 × 5 = 225 sq.m

area of the common part of cross road with 5 m width that lies at the

center of the park 5 × 5 = 225 sq.m

area of roads = area of first road +area of second cross road − common area

=( 350 + 225) −25

=575 − 25

=550 sqm

cost of the construction per sq.m = Rs.105

total cost =550 × 105 = Rs 57,750
