Question

The perimeter of a rectangular sheet is 100 cm and the length is 35 cm. Find its breadth and also find its area​

Answer 1

Answer:

Perimeter of rectangle=2(l+b)

100 cm =2(35+b)

100/2 =35+b

50=35+b

50-35=b

15=B

THEREFORE, BREADTH IS 15 cm.

AREA OF RECTANGLE=l×b

=(35×15) cm²

=525cm²

Answer 2

Answer:

↬ GIVEN :-

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

↬ TO FIND :-

• Breadth =?
• Area = ?

↬ SOLUTION :-

We know that

• Perimeter of rectangle = 2( Length + Breadth)

• ➢ 2( Length + Breadth ) = 100
• ➢ 2( 35 + Breadth ) = 100
• ➢ 35 + Breadth = 100/2
• ➢ Breadth = 50 - 35
• ➢ Breadth = 15 cm.

Now Area Of rectangular sheet-

• Area of Sheet = Length × Breadth
• = 35 × 15
• Area of sheet = 525 sq. cm

Hence Breadth is. 15 cm and Area is 525 sq. cm
