Question

a rectangle length is 9cm and perimeter is 26 cm what is width​

Answer 1

Answer:

it is easy

as perimeter is 2(l+b)

so 26=2(9+b)

26=18+2b

2b=26-18=8

b=8/2

b=4

width is 4

Answer 2

Answer :-

• Width of Rectangle =  4 cm

Given :-

• Length of Rectangle = 9 cm
• Perimeter of Rectangle = 26 cm

To Find :-

• Width of Rectangle =  ?

Explanation :-

Let the width of Rectangle to be 'x' cm.

$\rm \implies \bold { Perimeter \: of \: Rectangle = 2(L+B) }$

$\rm \implies 2(L+B) = 26 \: cm$

$\rm \implies 2(9+x) = 26 \: cm$

$\rm \implies (9+x) = \dfrac{26}{2} \: cm$

$\rm \implies 9+x = 13 \: cm$

$\rm \implies x = (13 - 9) \: cm$

$\underline { \boxed { \rm \implies \bold { x = 4 \: cm }}}$

Hence, the Width of the Rectangle is 4 cm.
