Question

4. The perimeter of a rectangular sheet is 100cm. if the length is 35cm, find its breath. also find the area. ​

Answer 1

$\bold{AnsweR:}$

Let length=l, breadth=b of rectangle ,

⇒ Perimeter=2(l+b) ,

⇒100=2(35+b) ,

⇒50=35+b ,

⇒b=15cm ,

Area=lb=35×15=525cm².

Answer 2

Answer:

Breadth= 15cm

Area= 525cm²

Step-by-step explanation:

Length= 35cm

Perimeter= 100cm

2(l+b)= 100

2(35+b)=100

70+ 2b= 100

2b= 100-70

2b= 30

b= 30/2

breadth= 15 cm

Area= Length× Breadth

= 35×15

= 525 cm²
