Answer:

  • The total number of stones required to pave the verandah are 200

Step-by-step explanation:

Given:-

  • a verandah is 40 m long and 15 m broad
  • A stone is 6 dm long and 5 dm wide

To Find:-

  • The number of stones required to pave the verandah

Formula used:-

  • Area of a rectangle is Length times breadth

Solution:-

As we know that,

  • 1 meter = 10 decimeters

The dimensions of the veradah will be,

  • Length = 40 × 10 = 400dm
  • Breadth = 15 × 10 = 150dm

Now let's find the area of the verandah,

:\implies \bf Area \; of \; verandah = 400dm \times 150 dm

:\implies \bf Area \; of \; verandah = 6000dm^2

The area of the verandah is 6000dm²

Now let's find the area of the stone,

:\implies \bf Area \; of \; stone = 6dm \times 5dm

:\implies \bf Area \; of \; stone = 30dm^2

The area of each of the stone is 30dm²

Now, the number of stones required will be,

:\implies \bf Area \; of \; verandah \; \div Area \; of \; stone

:\implies \bf No . of \; stones = 6000dm^2 \div 30dm^2

:\implies \bf No . of \; stones \; required = {\purple{\underline{\boxed{\frak{ 200 }}}\bigstar}}

The number of stones needed are 200

Therefore:-

  • The total number of stones required to pave the verandah are 200
