The cost of gravelling them at Rs. 1.20 per square meter = Rs . 1560
To find the area of roads :
It is given that
a rectangular lawn 80 m × 60 m has two roads each 10 m wide running in the middle of it.
Dimension of two roads are 80×10 and 60×10
Area of two roads = 80×10+60×10−10×10
=800+600−100
= 1300 sq. meter
To find the cost for gravelling
It is given that
The cost of gravelling the at Rs. 1.20 per sq. meter.
Therefore total cost = total area × cost per sq. meter
=1300×1.20
=Rs.1560
∴ The cost of gravelling them at Rs. 1.20 per sq. meter = Rs. 1560
Answer:
aera of bchg =80x5=400m²
aera of ijef=5x120=600 m²
total aera is 1000 m²
but the aera pqrs is adding two times so
1000-aera of pqrs
1000-25
975 m²
Step-by-step explanation:
total cost of construction
975x120
117000 rs
