Question

The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth.

Also find the area.

​

Answer 1

$\huge\underline\mathrm{SOLUTION:-}$

From the question it is given that,

• Perimeter of the a rectangular sheet = 100 cm
• Length of the rectangular sheet = 35 cm

We know that:

• Perimeter of the rectangle = 2 (Length + Breadth)

100 = 2 (35 + Breadth)

(100/2) = 35 + Breadth

50 - 35 = Breadth

Breadth = 15 cm

Then:

Area of the rectangle = Length × Breadth

= 35 × 15

= 525 cm²

Therefore:

• Area of the rectangular sheet is 525 cm².

✰✰ ANSWER ✰✰

$⇢Length=35cm.$

$⇢Breadth=?$

$⇢Perimeter=100cm.$

$\small{\bold{\bold{\bold{\purple{\sf{Perimeter\:of\:Rectangle= 2(l + b)}}}}}}$

$⇢2 (l + b) = 100$

$⇢2 (35 + b)=100$

$⇢35+b=\cancel\dfrac{100}{2}$

$⇢35+b=50$

$⇢b=50-35$

☛$B=15cm$

$\small{\boxed{\bold{\bold{\red{\sf{Area\:of\:Rectangle=l × b}}}}}}$

$⇢35×15$

☛${525cm}^{2}$

Area of Rectangular Sheet is 525cm²..
