Question

Find the cost of tiling a courtyard 30m long and 15m broad at the rate of Rs 5 per sq cm

Answer 1

Area of courtyard = length * breadth = 30*15 = 450 m²
Cost of tiling = 450 * 5 = ₹2200

Answer 2

L = 30 m and B = 15 m

Area of courtyard(courtyard is in a form of rectangle) = L x B

                                                                                         = 30 m x 15 m

                                                                                          = 450 m^2

                                                                                          = 4500000 cm^2

Cost of tiling                  = Rs 5 x 4500000

                                      =Rs 22500000
