Question

A floral design on the floor of a building consists of 280 tiles. Each tile is in the shape of a parallelogram of height 3cm and base 5cm. Find the cost of polishing the design at rs1.50 per square cm

Answer 1

The height of tile is 3cm and base is 5 cm

so the area of parallelogram is b*h
so area of llgm=5*3=15 cm²

so such their are 280 tiles
therefore area of the floor with tiles is 280*15=4200

so the cost of polishing the floor per cm²=₹1.5/cm2

so the cost =Area*Rate
=4200*1.5
=6300₹
