Answer:
W=30m L=90m
Step-by-step explanation:
A =2,700 m²
L=W+60
we know that area of a rectangle is A=L*W so we sustitute what we know
A=L*W
2,700 = (W+60)*W distribute
2,700 = W² +60W subtract 2,700 from both sides
W²+60W-2,700 =0
solve the quadratic equation with quadratic formula or on the calculator on the graph and will get W= -90 and W=30. Reject the -90 value because we can not have negative measurements. Our solution is W=30
L=A/W=2,700/30=90

Answer:
JL=2 units
Step-by-step explanation:
we know that
If k is the midpoint in the line JL
then
JL=JK+KL
JK=KL
substitute the given values
2x-5=3x-8
Solve for x
3x-2x=-5+8
x=3
so
JK=2x-5=2(3)-5=1 units
KL=3x-8=3(3)-8=1 units
therefore
JL=JK+KL=1+1=2 units
