Question

House 20 m long and 15 m width in surrounded by verandah of uniform width 3 m find the cost of flooring the verandahat ₹ 40 per sq.m

Answer 1

Area of verandah = [(25 x 20) -(20 x 15)] m2

= 200 m2

∴ Cost of flooring = Rs. (200 x 4)

= Rs. 800

Answer 2

Answer:

$area \: of \: a \: house \: = 20m \times 15m = 300$

$width \: of \: varandah = 3m$

$area \: of \: varandad = (300 - (20 - 3) \times (15 - 3))$

$300 - 204$

$= 96$

$cost \: of \: florring \: the \: varandah =$

$96 \times 200$

$= rs.19200$
