I have a project that calls for a piece of paper 35cm x 20cm. If the biggest piece of paper I have is 30cm x 30cm, what dimensions should I cut the shorter side to?

The shorter side should be cut to 23. 3cm

Step-by-step explanation:

The area of the required paper should be equal to the area of the paper available.

35*20=30 (30-x)

700 = 900-30x

30x=900-700

30x = 200

30x/30 = 200/30

x=6. 66
