# Problem 7: Find the value of x if the perimeter of the shape is given x below it : Perimeter = 28 cm x = ——————————————​

Solution:

Perimeter is defined as the total length of the boundaries;

So here;

$Perimeter= 2cm+1cm+2cm+3cm+6cm+4cm+1cm+2cm+x=21cm+x$

But perimeter is given as 28cm

it means;

$28=x+21$

so,

$x=7cm$
