Answer:
perimeter of rectangles = 2 ( l + b)
34 = 2 ( x + 2 + 3x - 4 )
34 = 2 ( 4x - 2 )
34 = 8x - 4
38 = 8 x
38/ 8 = x
thus , x = 4.75 inches
x=19/4
Step-by-step explanation:
perimeter is the sum of all sides
so
perimeter given is 34 = (x+2)+(x+2)+(3x-4)+(3x-4)
34=8x-4
34=8x
x=34/8 which reduces to 19/4
