Answer:

20 inches x 26 inches

Step-by-step explanation:

set up an equation: (2x)(x+7)=520

now just solve it

2x^2+14x=520

x^2+7x-260 = 0

factor: (x-13)(x+20)

x = 13 and -20

13 is the only one that works because you can't have a negative side length

13+7=20

13*2=26

lmk if you don't understand how to solve that equation
