Question

3. Area of the path around a square field is 425 m². Find the width of the path if the side of the square is 40 m.
Find the number of marble slabs, each of dimension 40 cm x 20 cm to be laid around a square park of side
18 m, to a width of 2 m.
​

Answer 1

Answer:

As we know that the formula of area of the path around a square is 4d ( L + B ).

So 4d ( l+b ) =425 meter square

Length is 40 amd breath is also 40.

Now take out the value of d .

Now find the area of the square

Area = l×b .

Now again take out the area of the marble . Area = l×b A= 40 ×20 =80 cm

Now divide the area of square with the area of marble 1600÷8 =200

Therefore number of marble required is 200.

Now again divide the area of of the path around a square by area of the .

The answer is here.

Answer 2

Answer:

As we know that the formula of area of the path around a square is 4d (L + B).

So 4d (1+b)=425 meter square

Length is 40 amd breath is also 40.

Now take out the value of d.

Now find the area of the square

Area = lxb.

Now again take out the area of the marble. Area = lxb A= 40 ×20=80 cm

Now divide the area of square with the

area of marble 1600÷8=200

Therefore number of marble required is 200.

Now again divide the area of of the path around a square by area of the .

The answer is here.
