1) ABF & EBD ARE SUPPLEMENTARY ANFLES (ABF + EBD =180)
2) FED=?. Note that FED=GEC=(16x-8).
Now in Triangle FED, the relation is (16x-8) + 35 + (2x+9) =180
hence x=8 & DEF=120
Set up the following equations:
110 represents the lengths of the length and width of the triangle, as you'll divide total perimeter of the rectangle, 220, by 2 to find the individual lengths. 20 is the difference between the length and width.
We'll use elimination for this system of equations, as there are opposite coefficients for W in both equations. Combine the two equations:
Divide both sides by 2 to get L by itself:
The length of the rectangle is 65 feet.Plug this value into the second equation:
Add W to both sides:
Subtract 20 from both sides:
The width of the rectangle is 45 feet.
