Answer:
7 inches by 19 inches
Step-by-step explanation:
We can use a system of equations for this.
<em>x=length</em>
<em>y=width</em>
2x+2y=52 (Perimeter)
xy=133 (Area)
We must find x and y that fit both these equations.
Hope this helps :)
set up a table (multiply across and add down - <em>don't add the middle column). Use the equation created by the "Total" row to solve for the variable.</em>
Quantity (times) % equals Total
Sol'n 1: x * .80 = (x)(.8)
<u>Sol'n 2: 15 - x * .30 = (15 - x)(.3)</u>
Total: 15 * .50 = .8x + .3(15 - x)
15(.5) = .8x + 4.5 - .3x
7.5 = .5x + 4.5
3.0 = .5x
6 = x
