Question

The perimeter of the rectangle below is 158 units. Find the value of z. 3z+ 3 4z−1

Answer 1

Answer:

11

Step-by-step explanation:

I assume that 3z + 3 and 4z - 1 represents the length and width of the rectangle.

thus, perimeter of a rectangle :

2 (a + b) = 158

2 ( 3z + 3 + 4z - 1 ) = 158

2 ( 7z + 2 ) = 158

7z + 2 = 79

7z = 77

z = 11
