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

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,

\[ x=7cm \]
