Answer:

Step-by-step explanation:

Height=5m

Length=12m

Width=10m

area of 4 walls:2*Height(Length+Width)

→ 2*5(12+10) m²

→ 10*22 m²

→ 220m²

Area of roof = Length*Width

→ 12*10 m²

→ 120m²

Total area → (220+120)m²

→ 340m²

Rate = m²/₹5.40

Price = 340/5.40

Answer:

total area = 2LH+2BH+LB

= 2.12.5+2.5.10+12.10

= 120+100+120

= 340m²

total cost = 340×5.40 = 1836ruppe
