Question

find the length and area breadth is given 50m and perimeter is given 250m .)

Answer 1

Let the length be 'x' and area be 'y'.

Given that the breadth = 50 m.

We know that Area = length * breadth

⇒ y = x * 50

⇒ y = 50x. ------ (1)

Now,

We know that Perimeter = 2(l + b)

⇒ 250 = 2(x + 50)

⇒ 250 = 2x + 100

⇒ 150 = 2x

⇒ x = 75.

Substitute x = 75 in (1) , we get

⇒ y = 50*75

⇒ y = 3750.

Therefore, length = 75 m and area = 3750 m^2.

Hope it helps!
