Question

the perimeter of a rectangular sheet is 100 cm.ig the lenth is 35 cm ,find its bradth also find the area​

Answer 1

Answer:

Let length=l, breadth=b of rectangle

⇒ Perimeter=2(l+b)

⇒100=2(35+b)

⇒50=35+b

⇒b=15cm

Area=lb=35×15=525cm

Answer 2

Answer:

Perimeter of rectangle =2(l+b)

Here, Length = 35 cm

Perimeter = 100 cm

Let the breadth of rectangle = x

So, Perimeter of rectangle = 2(35+x)

→ 100 = 70+2x

→ 100-70 = 2x

→30 = 2x

→x = 30/2

→x = 15

So, Breadth of the rectangular sheet = 15cm

Area of rectangle = l×b = 35×15

=525 cm²
