The area of a plastic sheet is 300 sq. cm and its length is 30 cm. What is the breadth of
the plastic sheet?​

Answer 1

• Breadth of rectangle is 10 cm.

Step-by-step explanation:

Given:-

• Area of plastic sheet is 300 cm².
• Length of plastic sheet is 30 cm.

To find:-

• Breadth of sheet.

Solution:-

• If in question length is given. Then the shape of sheet will be rectangle.

We know,

Area of rectangle = l × b

In which,

• l is length of rectangle.
• b is breadth of rectangle.

l = 30 cm.

Area = 300 cm².

Put l and b in formula :

➝ 300 = 30 × b

➝ 300/30 = b

➝ 10 = b

or, b = 10

Therefore,

Breadth of rectangle is 10 cm.

More information:-

• Rectangle is closed figure.
• It's opposite sides are equal and parallel.
• It's all angles are of 90°.
• Perimeter = 2×(l + b)

Answer 2

$\huge\bold{\mathtt{Question⇒}}$

The area of a plastic sheet is 300 cm² and its length is 30 cm. What is the breadth of

the plastic sheet?

$\huge\bold{\mathtt{Given⇒}}$

• Area = 300 cm²

• Length = 30 cm

$\huge\bold{\mathtt{To\:find⇒}}$

The breadth.

$\huge\bold{\mathtt{Solution⇒}}$

Let the breadth be b cm.

We know that:

Area of rectangle = (l × b) unit²

Where,

• l = length

• b = breadth

Here,

• l = 30 cm

• Area = 300 cm²

So, we can say-

30 × b = 300

➳ 30b = 300

Divide both sides by 30.

➳ 30b ÷ 30 = 300 ÷ 30

➳ b = 10

$\huge\bold{\mathtt{Hence⇒}}$

b = 10

Breadth = b cm = 10 cm

$\huge\bold{\mathtt{Therefore⇒}}$

The breadth of the plastic sheet is 10 cm.
