Question

The length of a rectangle is 2 cm more than 3 times its breadth. If the perimeter is 100cm, find the length and the breadth of the rectangle.

Answer 1

answer :

Step-by-step explanation:

let the breadth of rectangle= x

length will be= 3x+2

According to question ,

perimeter of rectangle= 2(l+b)

100= 2(3x+2+x)

50=4x+2

x = 48/4 = 12

so, lenght and breadth of triangle are 38cm and 12 cm respectively.

Answer 2

If,

• length = l cm
• breadth = b cm

Perimeter = 2(l + b) = 100 cm

⇒ l + b = 50 cm

⇒ (3b + 2) + b = 50 cm

⇒ 4b + 2 = 50 cm

⇒ b = 12 cm

So, l = 3(12) + 2 cm = 38 cm and breadth is of 12 cm.
