(ii) the cost of cementing the floor of the verandah at the rate of 200 per m²​

Answer 1

Answer:

i) 25.3125 m²

ii) ₹5062.5

Step-by-step explanation:

area of verandah= (lxb) m²

                            =(5x4) m² = 20m²

new dimensions with the width of verahdah: width= (4+2.25) = 6.25m

                                                                          length=(5+2.25) = 7.25 m

new area of room with verahdah= (6.25x7.25)

                                                      = 45.3125 m²

area of verandah=(45.3125-20)

                            =25.3125 m²

cost of cementing it= Rs. (25.3125 x 200)

                                = Rs. 5062.5
