Mathematical expressions allow us to relate numbers using mathematical symbols to make calculations. some examples are:
- 2 + 3 = 5
- 4 - 1 = 3
- 2 × 2 = 4
- 4 ÷ 2 = 2
- 2² + 1 = 5
- (1 + 2) + (2 × 1) = 5
- (2 + 3) - 4 = 1
- (2 + 2)² ÷ 4 = 4
- (2 ÷ 4)² × 4 = 1
- (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5
<h3>What is a mathematical expression?
</h3>
A mathematical expression is a sequence of characters that are intended to express a general relationship between the terms expressed in the formula.
Mathematical expressions generally have symbols like:
- Add +
- Subtraction -
- Multiplication ×
- Division ÷
- Exponent
- Equal =
- Parentheses ()
According to the above, some examples of mathematical expressions are:
- 2 + 3 = 5
- 4 - 1 = 3
- 2 × 2 = 4
- 4 ÷ 2 = 2
- 2² + 1 = 5
- (1 + 2) + (2 × 1) = 5
- (2 + 3) - 4 = 1
- (2 + 2)² ÷ 4 = 4
- (2 ÷ 4)² × 4 = 1
- (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5

Answer:
The area of the composite area is 400 square millimeters.
Step-by-step explanation:
The area of the composite figure (
), in square millimeters, is found by multiplying the area of the equivalent rectangle, in which a semicircle of the original rectangle is move to the opposite side of the figure, so that quantity of area is conserved:
(1)
Where:
- Width, in millimeters.
- Height, in millimeters.
If we know that
, the area of the composite figure is:


The area of the composite area is 400 square millimeters.
