Correct Option:
4th option is the correct answer
Solution:
The shape of Zorn's Patio is rectangular, as shown in the given image/ The perimeter of rectangle is calculated as:
Perimeter = 2 (Length + Width)
Width is given to be = (7x+4) feet
Perimeter is given to be = (30x+26) feet
Using the formula of perimeter we can write:
30x+26 = 2(Length + 7x+4)
Taking out 2 common from left hand side, we get:
2(15x+13) = 2(Length + 7x + 4)
Cancelling the common 2 from both sides, we get:
15x + 13 = Length + 7x + 4
⇒
Length = 15x + 13 - 7x -4
Length = 8x + 9
Therefore, the length of Zorn's Patio is (8x+9) feet
