Question

a rectangular grafty lawn measuring 45m by 25m has been surrounded by a path of 2m wide externally, Reckon the cost of gravelling the path at the rate of Rs. 4.30 per square metre. ​

Answer 1

Answer:₹1272.8

Step-by-step explanation:

dimensions = 45×25

width of path = 2 m

area of only lawn = 45×25

= 1125 m²

dimensions of lawn with path = 45+2+2 × 25+2+2

= 49×29

area of lawn with path = 49×29

= 1421 m²

area of path = (1421 - 1125)m²

= 296m²

rate of gravelling the path = ₹4.30/m²

so, total cost = ₹(296 × 4.30)

= ₹1272.8(ans)

Answer 2

Length: 45 m

Breadth : 25m

=45x25

=1125 m2

width of path = 2m

Dimensions of lawn with path= 45x2+2x25+2+2

= (49x29) m

=1421m 2

Area of path = (1421-112 s ) m 2

=296m2

Rate of gravelling the pata= Rs. 4.30

Rate of gravelling the total= 296x4.30 = Rs. 1272.8 (ans)
