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

= 120+100+120
= 340m²
total cost = 340×5.40 = 1836ruppe
