Question

the perimeter of a rectangular sheet is 100cm.If the length 35cm. find the breadth​

Answer 1

Step-by-step explanation:

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

2

.

Answer 2

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
