Question

how many slabs of cement are required to tile a platform of length 8m are breath 6m,if the length of each slabs is 4cm are breath 3 cm

Answer 1

Area of platform to be tiled [ Length=8m,Breadth=6m] = 48m² =480000cm²

Area of cement slab [ Length=4cm ,Breadth =3cm ] = 4×3=12cm²

Number of cement slabs required to tile the platform are 480000/12=40,000

Therefore,40,000 slabs are required .

Answer 2

Answer:

Number of slabs of cement are required to tile a platform are 40000 .

Step-by-step explanation:

Formula

Area of a rectangle = Length × Breadth

As given

Platform of length 8m are breath 6m .

Area of the platform = 8 × 6

                                  = 48 m²

As

1` m = 100 cm

Thus

48 m² = 48 × 100 × 100 cm²

           = 480000 cm²

if the length of each slabs is 4cm are breath 3 cm .

Area of a slab = 4 × 3

                        = 12 cm²

Let us assume that the numbers of slabs of cement are required to tile a platform be x .

Equation becomes

12 × x = 480000

12x = 480000

$x = \frac{480000}{12}$

x = 40000

Therefore the number of slabs of cement are required to tile a platform are 40000 .
