Problema Solution
Marissa is designing a poster to promote the Talbot Street Art Fair. The width of the poster will be two-thirds of its height, and its perimeter will be 100 in. Find the dimensions of the poster.

Let 'w' and 'h' stand for the width and height of the poster. We can write:
w=(2/3)h
2w+2h=100
Using Algebrator to solve for 'w' and 'h', we get:
h=30 in
w=20 in
