Answer 1

Answer:

Step-by-step explanation:

Length(L) = 8m

Width(W) = 90cm = 0.9 m

I) area= LxW = 8x0.9 = 7.2m

ii)cost of carpet= 34 per sq. centimetre

So total cost = area x cost = 7.2x34= 244.8 per sq. centimetre

Answer 2

Length of hallway =8m= 800cm

Wide of hallway =90cm

Area of hallway=length×breadth

$area \: of \: hallway = 800 \times 90 = 72000 {cm}^{2}$

$carpet \: cost = 4 {cm}^{2}$

$for \: 72000 {cm}^{2}$

=72000 X 4 =288000₹
