Question 211034
L=10W-2
2L+2W=62
2(10W-2)+2W=62
20W-4+2W=62
22W=62+4
22W=66
W=66/22
W=3 FT.
L=10*3-2
L=30-2
L=28 FT.
PROOF:
2*28+2*3=62
56+6=62
62=62
-------------------------------------
2(3W+7)+2W=78
6W+14+2W=78
8W=78-14
8W=64
W=64/8
W=8 IN.
L=3*8+7
L=24+7
L=31 IN.
PROOF:
2*31+2*8=78
62+16=78
78=78
