Question

The perimeterr of a rectangle is 54cm.if it's width is 2 cam more than one fourth of its length, then its length(in cm) is equal to?

Answer 1

12 cm

If its width is 2 cm more than one-fourth of its length. What is its length? 12 cm.

Answer 2

Answer:

Length of a rectangle is 20 cm

Step-by-step explanation:

• The perimeter of a rectangle is 54 cm

• Width is 2 cm more than one fourth of its length

Find :

• Length of a rectangle

Solution :

Let,

Length of a rectangle = x

Width of a rectangle = 1/4 x + 2

(0.25x + 2)

1/4 = 0.25

So,

Perimeter of rectangle = 2 (length + width)

➨ 2 (x + 0.25x + 2) = 54

➨ 2x + 0.5x + 4 = 54

➨ 2.5x = 54 - 4

➨ 2.5x = 50

➨ x = 50 / 2.5

➨ x = 20

Therefore,

Length of a rectangle is 20 cm
