Question

Find the cost of flooring the verandah at the rate of ₹10 per sqm if the length and breadth are in the ratio 4: 3 and its perimeter is 56m.

Answer 1

Answer:

Let The length and breadth be x So 4x and 3x

Perimeter =56m

2(l+b)=56

2(4x+3x)=56

2(7x)=56

2*7x=56

14x=56

x=56÷14

x=4

Length=4*4=8m

Breadth=4*3=12m

Area of verandah=L*B

=8*12

=96msquare

Cost of flooring at 1metre square=ruppes10

Cost of flooring at 96m square=96*10

=ruppes960
