Question

Total expenditure to paste a paper of breath 60cm and the rate of 4 per m is rupees 580 find the height of room? Length 8.5m and breath 6m.

Answer 1

Step-by-step explanation:

Given, cost of papering the wall is Rs 3150 at Rs 14 per sq. m. Height of the room is 5m and length and breadth are in ratio 4:1.

Area of wall to be papered=rateofpaperingpermetercostofpaperingthewall=143150=225m2

The height of wall=5 cm. Let the length of the wall be 4x and breadth be x.

Surface area of four walls=2h(l+b)

  or,225=2×5(4x+x)or,225=10(5x)or,225=50xor,x=4.5

Length of wall=4x=5×4.5=18m.

Breadth of wall=x=4.5m
