Answer:
Length = 24 and Width = 81
Step-by-step explanation:
Let Width be W
then Length = W-57
Perimeter of rectangle = 2(Length + Width)
=2 (W-57+W)= 210
4W- 114= 210
4W= 324
W= 81
Then Length = 81-57 = 24

Answer:
Option A, 25.25
Step-by-step explanation:
x = (54+204)/2 = 129
180-129 = 51
So,
(3z+1+z)/2 = 51
or, 4z+1=102
or, 4z=101
or, z = 25.25
