Answer:
22cm by 6cm
Step-by-step explanation:
Width = x
Length = 3x + 4
x + x + 3x + 3x + 4 + 4 = 8x + 8
Perimeter = (8x + 8) cm
56 - 8 = 48cm
48/8 = 6
6 = x
Width = 6cm
Length = 22cm

D. X = 8 , Y = 6
3x - 14 = x + 23x - x = 2 + 142x = 162x / 2 = 16/2x = 8
To check: 3x - 14 = x + 2 ; 3(8) - 14 = 8 + 2 ; 24 - 14 = 10 ; 10 = 10
4y - 7 = y + 114y - y = 11 + 73y = 183y / 3 = 18 / 3y = 6
To check: 4y - 7 = y + 11 ; 4(6) - 7 = 6 + 11 ; 24 - 7 = 17 ; 17 = 17
