Question

the perimeter of a rectangle is 14cm and it's width is 2.25 cm find it's length. Urgent plz.​

Answer 1

Answer:

P=2(l+w)

Solving forl

l=P

2﹣w=14

2﹣2.25=4.75cm

Answer 2

Answer:

Length of rectangle = 4.75 cm

Step-by-step explanation:

Given:

• Perimeter of rectangle = 14 cm
• Width or Breadth = 2.25 cm

To find:

• Length = ?

Solution:

Let the length of rectangle be ‘l’

We know that:

Perimeter of rectangle = 2 (l + b)

Where:

• b is the breadth of rectangle.

Substitute the given values in the above formula.

14 = 2 (l + 2.25)

⇒ 14 = 2l + 4.5

⇒ 14 - 4.5 = 2l

⇒ 9.5 = 2l

⇒ l = 4.75 cm.

∴ Length of rectangle = 4.75 cm
