Question

the length and width of a rectangle are in ratio of 4:2 . if it's perimeter is 48 cm , find its length and width .
​

Answer 1

Step-by-step explanation:

let l be 4x

and b be 2x

$2(l + b)$

$2(4x + 2x)$

$2 \times 6x$

$12x$

$48 = 12x$

$x = 48 \div 12$

$x = 4$

$l = 4 \times 4$

$l = 16$

$b = 2 \times 4$

$b = 8$

Hope this helps you.
