Question

The perimeter of a rectangle is 26cm and its width is 2 whole 3/4 cm . Find its length​

Answer 1

Answer:

Perimeter of rectange =2 (I +b)

13=2(I +2 3/4)

13=2(I +11/4)

I+11/4=13/2

multiply by 4. (I cm)

4 I+11= 26

4 I=15

I=15/4=3 3/4

length I=3 3/4

Answer 2

Answer:

Here ,

Perimeter = 26 cm.

width =( 2)¾ cm. = 11/4 cm.

As we know ,

Perimeter of rectangle = 2 ( length + width)

=> 26 = 2 ( length+ 11/4)

=> 13 = length + 11/4

=> length = 13 - 11/4

=> length = (52-11)/4

=> length = 41/4 cm.

So, length is 41/4 cm.
