Answer:
1) 4 ft
2) Length =69
Width=64
Step-by-step explanation:
1) 2x-2+2x-2+x-2+x-2=x+x-1+x-1
6x-8=3x-2
6x-3x=-2+8
3x=6
x=2
plugging it back in, we get for the triangle
2+2-1+2-1=4 (same answer for the rectangle, although it would have a width of zero)
2) w+w+w+5+w+5=266
4w+10=266
4w=266-10
4w=256
w=64
l=64+5=69
