Answer: Rounded, the diagonal is 4.6 feet

Step-by-step explanation: Use the Pythagorean Theorem: c² = a² + b²

Then take the square root of c² to find the length

2.25² =5.0625 This is a²

4² = 16 This is b² Add a² + b² to get c²

5.o625 + 16 = 21.0625 This is c²

√21.0625 = 4.589389938 This is the square root.

Round this to common measurements or "significant digits" 4.6 feet.

X+2a = 16+aX-6a
8X - 16 = aX-2a
8(X-2) = a(X-2)
(X-2)/(X-2) = a/8
1 = a/8
a= 8
