Question

A rectangular park measures 28m by 14m.A path 2.5m wide is constructed all around it.Find the cost of paving the path with cement tiles 47m by 40m at the rate of Rs/ 4.80 per tile​​

Answer 1

Answer:

Area of park=L×B where L and B are length and breadth of park.

=>L×B=45×30=1350(m)2

area of bigger rectangle including path=>L2×B2=(45+2.5)(30+2.5)

=>47.5×32.5=1543.75(m)2

area of path=1543.75-1350=193.75(m²)
