Question

Two Cross-roads each 4 m wide, run through,
the centre of a rectangular park of dimen-
sions 70 m by 40 m, are parallel to length and
other parallel to breadth. Find the cost of
levelling the roads at Rs. 8 per m² and also
the cost of planting flowers in remaining part
of park at Rs. 6 per m².​

Answer 1

Answer:

RS 3456 and RS 14208.

Step-by-step explanation:

{4×40=160}+{(70×4)-8}=432×8=3456

{70×40}-432=2368×6=14208

Answer 2

Answer:

Area of road=70*4+40*4-4*4

Step-by-step explanation:

=280+160-16=440-16=424

So cost of leveling@₹8 per sq m=424*8=₹3392 ANSWER

(2) Remaining area of garden=(70*40)-424

=2800-424

=2376 sq m

Cost of planting flowers in this area is 6*2376

=₹ 14256 ANSWER.
