The area of trapezium. If the parallel side of trapezium are 9.5cm and 12.5cm and the altitude is 11cm find the length of the side of the square

uh, which square?

yes

To find the area of a trapezium, you can use the formula:

Area = (a + b) * h / 2

Where:
a and b are the lengths of the parallel sides of the trapezium.
h is the altitude, which is the perpendicular distance between the parallel sides.

In your question, the lengths of the parallel sides are given as 9.5cm and 12.5cm, and the altitude is given as 11cm.

Using the formula, we can substitute the values:

Area = (9.5 + 12.5) * 11 / 2
Area = 22 * 11 / 2
Area = 242 / 2
Area = 121 cm²

Now that we know the area of the trapezium is 121 cm², we need to find the length of the side of the square.

To find the length of the side of a square, we can use the formula:

Area of Square = Side²

In this case, the area of the square is equal to 121 cm².

Using the formula, we can solve for the side length:

Side² = 121
Taking the square root of both sides, we get:

Side = √121
Side = 11 cm

Therefore, the length of the side of the square is 11 cm.
