Question

A veranda 1.25m is constructed all along outside of a room 7.5m long and 5m wide.Find the area of the verandah . the cost of the the cementing the floor of the verandah at the rate of rupees 15 per metre square​

Answer 1

Step-by-step explanation:

PQ = 5 m

PS = 7.5 m

Area of PQRS = 5 × 7.5

= 37.5 m²

AD = 7.5+ 1.25 + 1.25 = 10 m

AB = 5 + 1.25 + 1.25 = 7.5 m

Area of ABCD =7.5 × 10

= 75 m²

Hence,

Area of Verndah = 75 - 37.5

= 37.5 m²

Cost of cementing of 1 m² = R.s. 15

Cost of paving 1544 m² = 37.5 × 15 = R.s. 562.5
