Question

if the perimeter of a rectangle is 35 cm and the breadth is 10 find the area of the rectangle​

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

Let length= l, breadth= b of rectangle

→ Perimeter= 2(1+ b)

→ 100 = 2(35 +b)

→ 50 = 35 +b

→ b = 15cm

Area= l×b = 35 x 15 = 525cm^2
