Question

If the area of a rectangle is 20 cm2 and its length is 5 cm, its breadth is

Answer 1

☆ Solution ☆

Given :-

• The area of a rectangle is 20 cm².

• The length of a rectangle is 5 cm.

To Find :-

• The breadth of a rectangle.

Step-by-Step-Explaination :-

Let,

• The breadth of a rectangle be b .

Now,

As we know that :-

Area of rectangle = length × breadth

Where,

• Area of rectangle = 20 cm²

• Length of rectangle = 5 cm

• Breadth of rectangle = b

Putting the respective value,

20 = 5 × b

20 = 5b

20/5 = b

4 = b

Hence,

The breadth of the rectangle is 4 cm .

Answer 2

Question:-

If the area of a rectangle is 20 cm² and its length is 5 cm, its breadth is

To Find:-

• Breadth of rectangle

Given:-

• Length = 5 cm
• Area of rectangle = 20 cm²

Solution:-

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \mathfrak{ \underline{ \green{ Formula \: to \: calculate \: the \: area \: of \: rectangle}}}$

$\boxed{ \: \: \: \star \: \: \: { \underline{ \mathfrak{ \large{ \red{ area = length \times breadth}}}}}}$

According to question,

$\large{ \sf \longmapsto \: \: \: \: \: \: \: \: \: \: \: breadth \times 5 = 20}$

$\large{ \sf \longmapsto \: \: \: \: \: \: \: \: \: \: \: breadth = \frac{20}{5} }$

$\large{ \sf \longmapsto \: \: \: \: \: \: \: \: \: \: \boxed{ \boxed{\blue{ \mathfrak{breadth = 4 cm}}}}}$

Hence,

• The breadth of rectangle is 4 cm
