Answer:

1) 5

2) 25

Step-by-step explanation:

Since a square has equal sides, we have 4x=2x+10

2x=10

x=5

The area of a square is 5 squared, which is 25.

4x = 2x + 10
because it’s a square and all sides are equal.
Then combine like terms.
-subtract 2x from both sides
2x=10
Then divide both sides by 2 to get x alone and get your x value.
x=5

With that knowledge just find one side’s length and square it.
4(5) =20
20^2 =400 units squared
