Answer:

56 units, 28 units

Step-by-step explanation:

<u>Rectangle has equal diagonals:</u>

JL = MK

<u>Substitute and solve for x:</u>

5x + 1 = 8x - 32
8x - 5x = 1 + 32
3x = 33
x = 11

<u>Find the length of the diagonals:</u>

JL = MK = 5*11 + 1 = 56 units

<u>Diagonals of the rectangle bisect each other:</u>

KN = MK / 2 = 56/2 = 28 units
