Question

The length of a hall exceeds its breadth by 12m, if the perimeter of the hall is 128m, find the cost of carpeting it at 25rs per sq.m.

Answer 1

Answer:

17,325 rs

Step-by-step explanation:

let breath be x

then length = x+12

x + x + 12 + x + x + 12 = 128

4x + 24 = 128

4x = 104

x = 21

x + 12 = 33

Area = 33*21

= 693m^2

25 rs per meter square, so
693*25

= 17325rs

Hope it helps!
