The simplified expression is
Explanation:
The given expression is
Let us simplify the expression.
Multiplying the numbers in the numerator, we have,
Dividing the term 144 by 3, which results in 48.
Thus, we have,
Applying the fraction rule , we get,
Applying the exponent rule , we have,
Thus, the simplified expression is
Answer:
The area of the trapezium is 18 ft²
Step-by-step explanation:
Given;
Two parallel sides of the polygon as follows;
The first parallel side = 1 ft + 4 ft = 5 ft
The second parallel side = 4 ft
If this polygon is rotated 90 degrees, it forms a trapezium with a height of 4 ft.
The area of a trapezium is calculated as;
Therefore, the area of the trapezium is 18 ft²
