4a-13=19 add 13 to both sides
4a=32 divide by 4 on both sides
a=8
For a parallelogram, the parallel sides must be the same length. This means you can set their lengths equal to each other. Get like terms on the same side to calculate x.
3x-5=2x+3
3x-5+5=2x+3+5
3x=2x+8
3x-2x=2x-2x+8
x=8
x=8
we know that
if JKLM is a rectangle
then
diagonals
MK=JL
so
MK=2*MN------> MK=2*25 ft------> MK=50 ft
JL=MK----> JL=50 ft
therefore
the answer is
JL is 50 ft
