Answer:

x = 89

(x + 2) = 89 + 2 = 91

Explanation:

The perimeter of shapes always total 360 degrees so the equation should always equal 360 degrees.

(x + 2) + (x + 2) + x + x = 360

Collect like terms: 4x + 4 = 360

To get the value of x subtract 4 from both sides: 4x = 356

x = 89

Answer:

Explanation:

Perimeter = x + x +20 +x + x+20

= 4x + 40

Area = x * (x+20)

= x*x + x*20

= x² + 20x
