Remember: P%5BR%5D=2%28L%2BW%29, working eqn
Given: P=112meters
L=4m%2BW----> subst. working eqn
112=2%284%2BW%2BW%29---->112%2F2=%28cross%282%29%284%2B2W%29%29%2Fcross%282%29
56=4%2B2W----->56-4=2W
cross%282%29W%2Fcross%282%29=cross%2852%2926%2Fcross%282%29
highlight%28W=26meters%29---> EXACTLY 26 meters, ANSWER
L=4%2B26=30meters
Check:
112=2%2830%2B26%29
112=2%2856%29
112=112
