The Perimeter of the rectangle below is 94 units find the length of side peek you write your answer without variables

ivolga24 [154]

Answer:

DC = 21 ; BC = 26

Step-by-step explanation:

The perimeter of a rectangle is given by :

P = 2(length + width)

2x + 3

3x - 1

Perimeter, P = 94

Hence,

94 = 2(2x +3 + (3x - 1))

94 = 2(2x + 3 + 3x - 1)

94 = 2(5x + 2)

94 = 10x + 4

94 - 4 = 10x

90 = 10x

x = 90 /10

x = 9

DC = 2x + 3 = 2(9) + 3 = 18 + 3 = 21

BC = 3x - 1 = 3(9) - 1 = 27 - 1 = 26
