Perimeter = 2L + 2W
Given:system%28P=64m%2CL=8%2B2W%29

Substitute given to our Eqn,
highlight%2864%29=2%28highlight%288%2B2W%29%29%2B2W
64=16%2B4W%2B2W
64-16=6W
6W=48 ----> cross%286%29W%2Fcross%286%29=cross%2848%298cross%286%29
red%28W=8m%29
Also,
L=8%2B2%28highlight%288%29%29=8%2B16
red%28L=24m%29

Check as per our Eqn,
64m=2%2824%29%2B2%288%29
64m=48m%2B16m
64m=64m
