Answer:

7) area of outer rectangle is 4×7.5 =30 m²

area of inner square is (2)²= 4 m²

as there are 3 square so total area is 3×4=12 m²

so left over land is 30-12=28 m

8) 2000 per liter

each liter covers 10m²

gate base=25m

height=10m

area of the gate is

bh= 25×10=250 m²

1 lit = 10 m²

x lit =250 lit

250/10 = 25 liter

2000 is fir 1 lit

for 25 lit =2000×25

=50000

9) 24+4+4+12=44m²

10) family room area = 7×4=28m²

lounge room area = 6×5=30 m²

dinning room area = 4×4.5=18 m²

total area is 28+30+18

=76m²

total cost as 70 rs per m²

70×76= rs 35720

cost as 2300 per room will be

6900

so giving it on per room basis will be cost effective
