Ok so I uploaded the picture of how to do the promblem step by step so you know :)
The answer is 1 because 8.2/8688 = <span>0.00094383057</span>
Simplies form of 3/8 is 1/4
L=W+12
2L+2W=48
2(W+12)+2W=48
2W+24+2W=48
4W=48-24
4W=24
W=24/4
W=6 ANS. FOR THE WIDTH.
L=6+12=18 ANS. FOR THE LENGTH.
PROOF:
2*18+2*6=48
36+12=48
48=48
Hope this helps:)
3 hours
On the way there, 1.5x12 = 18
On the way back, 1.5x10 = 15
