Question

the perimeter of a rectangle is 13 cm and its width is 23/4cm and find its length

Answer 1

Perimeter = 13cm.
Width =23/4cm
Length = perimeter /2 - width.
Therefore, length = 13 /2 - 23/4 =
3/4cm.

Answer 2

☺hi !!!!!!!!!

this is your answer dear user...

Given :-
perimeter of a rectangle is 13 cm
width (breadth (b)) = 23/4cm = 5.75cm


let length be ' l '

perimeter of rectangle = 2( l +b )
$= > 13 = 2(l + 5.75) \\ \\ = > \frac{13}{2} = (l + 5.75) \\ \\ = > 6.5 = l + 5.75 \\ \\ = > 6.5 - 5.75 = l \\ \\ = > l = 0.75$
length = 0.75cm = 7.5mm


CHECK
perimeter of rectangle
= 2(l + b)
= 2 (0.75+5.75)
= 2 (6.50)
= 13cm


I hope this will be helpful for you!!!!!!! ☺
