<h3>What are mathematical operations?</h3>- An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
- The operation's arity is determined by the number of operands.
- A mathematical action is called an operation.
- Mathematical operations include addition, subtraction, multiplication, division, and finding the root.
So, the area of the figure:
Where x = 4, so the expression will become:
- x² + x² + x + x
Now, do the mathematical operations to get the area of the figure as follows:
- x² + x² + x + x
- 4² + 4² + 4 + 4
- 16 + 16 + 8
- 40
'
Therefore, using mathematical operations we can conclude that the area of the given figure is 40 units².
