Question

A Hankerchief measures 22 cm long and 20 cm wide. Jenny wants to put a lace around it. How many cm of lace she buy to decorate its side?​

Answer 1

Answer:

You should find the perimeter using perimeter of rectangle formula

Step-by-step explanation:

Perimeter of a rectangle = 2×(l+b)

Here L(length) = 22cm and B(Breadth) =20cm.

Perimeter = 2×(22+20)

= 2×42

=84cm.

So she should buy 84cm of lace to decorate its side

Answer 2

Concept:

Perimeter of a rectangle is the total distance covered by its boundries or sides

Perimeter of Rectangle $=2[L+B]$

Here $L=lenght$

$B=breadth$

Given:

$L=22cm\\B=20cm$

Find:

How $cm$ of lace she buy to decorate its side.

Solution:

By considering the given data

Perimeter

$=2\times [22+20]\\=2\times 42\\=84 cm$

Hence, she should buy $84cm$ of lace to decorate its side.
