W - width
l - length
p - perimeter
The perimeter is 72 cm (p=72).
The length is twice the width (l=2w).
The formula for perimeter is 2w+2l=P.

Check the answer:

The length of the photo is 24 cm, the width of the photo is 12 cm.

Answer:
solution set are


Step-by-step explanation:
we are given system of equation as


For finding solution set , we can draw graph of both equations
and then we can find intersection point
the intersection point will be our solution set
we get graph as
So, solution set are
