Width= w
lenght = 6 width = 6w

area= 284 yd²
       = (width)(length)
       = (w)(6w)
       = 6w²

6w²= 284
w²= 284/6
    = 47.333333....
w=√47.2
  = 6.88 inches

perimenter = 2width+ 2 lenght
                  = 2(w) + 2(6w)
                  = 2w+12w
                  = 14w
                  = 14(6.88)
                  = 96.28 inches

Look at pseudocode segment below. y ← x + x + x + x + x // line a z ← y + y + y // line b If x = 6 before this segment is execut
r-ruslan [8.4K]

Answer:

90.

Step-by-step explanation:

We have two lines of code:

y ← x + x + x + x + x

z ← y + y + y

and, x=6 before the execution. Then, when the program starts to run we obtain:

y ← 6 + 6 + 6 + 6 + 6

y ← 30

z ← 30+30+30

z ← 90.

Then, the value of z after excecution is 90.
