a tabletop is in the shape of a parallelogram. it's base is 5m and altitude is 3m. find the cost of painting the table top at the rate of rs 20 per m2

Answer 1

Area of parallelogram = bh.

Here, Base = 5m
Height = 3m .

Area = 5m * 3m = 15m²


Given , The cost of painting the table top = 20 Rs per m² .

Cost = 20 * 15 = 300 Rs .

Answer 2

area of Parallelogram=base ×height
therefore 5m×3m=15m2
now cost of painting =(15×20)rupees=300Rupees
