Question

A 36-m-long, 15-m-borad verandah is to be paved with stones, each measuring 6 dm by 5 d m. How many stones will be required?

Answer 1

Answer:

1800 stones

Step-by-step explanation:

Given: length of verandah = 36 m

           breadth of verandah = 15 m

           length of stone = 6 dm=0.6 m

           breadth of stone = 5 dm= 0.5 m

area of verandah= area of rectangle

                            = l*b

                            = 36*15

                            = 540 m^2

area of 1 stone = area of rectangle

                         =l*b

                         =0.6*0.5

                         = 0.30 m^2

No. of stones required to pave the verandah = area of verandah ÷ area of 1                                stone

                                                                           = 540/0.3

                                                                           = 1800
