Answer:
Step-by-step explanation:
set jk and kl equal to each other bc they are the same length (we know this bc of the midpoint)
3x - 1 = 2x + 8
x = 9
substitute 9 in an equation
2(9) = 8 = KL
18 + 8
26 = KL
since KL is the same length as JK we can just multiply 26 * 2
JL = 52

Answer:
Total area = 12x^2 + 2x
Perimeter = 18x+4
Step-by-step explanation:
Divide the figure into two separate shapes to make the question easier.
Area = lw
Area (bigger shape) = (3x)(3x)
Area (bigger shape) = 9x^2
Area = lw
Area (smaller shape) = (3x+2)(x)
Area (smaller shape) = 3x^2+2x
Add the areas of the bigger and smaller shapes to get the total area:
Total area = 9x^2 + 3x^2 + 2x
Total area = 12x^2 + 2x
To find the perimeter, add the lengths of all the sides.
(3x)+(3x)+(3x)+(3x)+(3x+2)+(3x+2)
(12x)+(6x+4)
perimeter = 18x+4
x = 
multiply all terms on both sides of the equation by the lowest common multiple of 3 and 8, that is 24
24 × 
= 24 × 
+ 2 × 24
16x = 3(x - 1) + 48
16x = 3x - 3 + 48
16x = 3x + 45
subtract 3x from both sides
16x - 3x = 45
13x = 45
divide both sides by 13
x =
