Question

The perimeter of rectangle is 13cm and its width is 2 3/4 cm Find the length

Answer 1

Answer:

2(l+b)=13 cm

2 (l+11/4)=13

l+11/4=13/2

so, l= 13/2-11/4=(26-11)/4=15/14 cm= 1whole 1/14 cm

hope you understood! !

Answer 2

Answer:

3/4 = length

Step-by-step explanation:

$p = 2(l + b) \\ = > 13 = 2(l + \frac{23}{4} ) \\ = > \frac{13}{2} = l + \frac{23}{4} \\ = > \frac{13}{2} - \frac{23}{4} = l \\ = > \frac{26 - 23}{4} =l \\ = > \frac{3}{4} = l$

Hope this answer will help you!
