Line jk bisects line lm at point j. find jm if lj=23 centimeters

The length of JM is 23 centimeters.

Step-by-step explanation:

It is given that Line JK bisects line LM at point J. It means J is the midpoint of line LM.

A midpoint divides a line in two equal parts.

J is midpoint of LM, so we can say that the distance between L ans J, J and M are same.

It is given that LJ=23 centimeters. Substitute LJ=23 in the above equation to find the value of JM.

Interchanging the sides, we get

Therefore the length of JM is 23 centimeters.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
