Question

the perimeter of a rectangle is 13 and its width is 2 and 1/2 . then its length is​

Answer 1

Answer: 4 cm

Explanation :

☯️Given :

Breath = 2×1/2 = 5/2

☯️Solution:

Let the length of the rectangle be x.

Now,

Perimeter = 2(length + breath)

= 2(x + 5/2)

Putting perimeter of rectangle = 13 cm

13 = 2(x + 5/2)

13/2 = x + 5/2

x = 13/2 - 5/2

x = 8/2

x = 4

Hence, the length of the rectangle is 4 cm.
