Question

how to find length if the area is 220sq.cm and the breadth =20 cm. what is the length ?

Answer 1

Answer:

Length = 11 cm

Step-by-step explanation:

Area = 220 cm²

Breadth = 20 cm

Length = ??

Area = 220

Length * Breadth = 220

Length * 20 = 220

Length = 11 cm

Answer 2

Given:

A rectangle with

• Area = 220 sq.cm
• Breadth = 20 cm

What To Find:

We have to find the length.

How To Find:

To find length, we will use the formula,

• Area = Length × Breadth

Solution:

Using the formula,

⇒ Area = Length × Breadth

Substitute the values,

⇒ 220 sq.cm = Length × 20 cm

Take 20 cm to LHS,

⇒ $\sf{\dfrac{220}{20} = Length}$

Cancel the zeros,

⇒ $\sf{\dfrac{22\!\!\!\not0}{2\!\!\!\not0} = Length}$

Also written as,

⇒ $\sf{\dfrac{22}{2} = Length}$

Divide 22 by 2,

⇒ $\sf{11 \: cm = Length}$

∴ Hence the length is 11 cm.
