Answer:
The poster is 11 inches wide and 19 inches in height.
Step-by-step explanation:
We take the given equation: (x^2+2x-15) and we add in 14 as our x variable:
((14)^2+2(14)-15) the answer we get from that is 209. The area of the poster is 209 square inches. Then we find the width by taking (x-3) in this case x is 14 so the width of the poster is 11. In order to find the height we divide the height by the width and we get 19.
Therefore:
Height= 19 Inches
Width= 11 Inches
Total Area= 209 Square Inches
