Answer:
C = a² + 2ab + b²
Step-by-step explanation:
From the diagram above,
Let the dimension of the square be
A (length) = (a + b) and B (breadth) = (a + b).
Area of the square is A*B
A * B = (a + b) * (a + b)
Area = a² + ab + ab + b²
Area = a² + 2ab + b².
Therefore the expression that defines the area of the square is a² + 2ab + b².

The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let the distance travelled in the first day be 20 miles. If the same time was travelled for 3 days, hence:
3(20) + x = 79
x = 19 miles
The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.
