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

Answer:

Perimeter = 2(length×breadth) = 100

Given that,

Length = 35 cm

Breath = ?

So, 2( 35×b ) = 100

35+ b = 100/2 = 50

Therefore,

»» B = 50-35

= 15

Area of the rectangular sheet

»» Length×Breadth

»» 35 × 15 = 525 cm²

hope it helps you.

Answer 2

Given :-

The Perimeter Of A Rectangular Sheet is 100 cm. If the length is 35 cm

To Find :-

• The Breadth ?
• The Area

Formula Used :-

$\bigstar$ Using Perimeter:

$\dashrightarrow \sf\boxed{\bold{\pink{P/2 - l units}}}$

$\bigstar$ Using Rectangle Formula :

$\dashrightarrow \sf\boxed{\bold{\pink{l × b sq. units}}}$

Solution :-

Given Equation :

Perimeter = 100cm

Length = 35cm

Let's Find The Breadth:-

➝ 2(L+B) = 100

➝ 2(35+B) = 100

$\sf \implies 35 + b = \frac{100}{2}$

$\sf \implies b = 50 - 35$

$\sf\boxed{\bold{\red{b = 15cm}}}$

∴ Breadth Of The Rectangular Sheet = 15cm

Let's Find The Area:-

$\sf\boxed{\bold{\red{Area \: Of \: The \: Sheet \: ^{lxb} }}}$

◆ 35×15

◆ 525 sq.cm

◆ 525cm²

So, The Area Of The Rectangular Sheet

$\sf\therefore=Area \: If \: The \: Sheet =525cm²$
