Question

Christy wants to put a lace border all around a rectangular table cover 3m long and 2m wide(breadth) .Find the perimeter of a rectangular table cover​

Answer 1

Given: The length of the rectangular table cover is $3$m., and the width of the rectangular table cover is $2$m.

We have to find the perimeter of a rectangular table cover.

As we know that the formula to calculate the perimeter of a rectangle is$P=2(l+w)$.

By using the above formula, we are finding the perimeter of a rectangular table cover.

We are solving in the following way:

We have,

$l=3 and w=2$

The perimeter of a rectangular table cover will be:

$P=2(l+w)$

$=>P=2(3+2)\\=>P=2(5)$

Solving the above equation further we get,

$=>P=10$cm.

Hence, the perimeter of a rectangular table cover will be $10$cm.

Answer 2

Given,

Christy wants to put a lace border all around a rectangular table cover $3m$ long and $2m$ wide(breadth).

We have to find the perimeter of a rectangular table cover

In order to find the perimeter of rectangular cover  $3m$ long and $2m$ wide(breadth).

Formula,

Perimeter of a rectangle $= 2(l+b)$

Here,

Length $=3m$

Breadth $=2m$

Substitute the given values in the above formula,

Perimeter $= 2(3+2)$

$= 2(5)$

$=10$

Therefore, the perimeter of a rectangle table cover is $10m$.
