The area of trapezium ABCD is calculated using the formula for a trapezium's area, which results in an area of 38 square inches.
To calculate the area of a trapezium, we can use the formula: Area = ½ * (sum of the lengths of the parallel sides) * (distance between them). In the case of trapezium ABCD, where AB = 7 inches, CD = 12 inches, and the perpendicular distance between AB and CD is 4 inches, the area would be:
Area = ½ * (AB + CD) * height
= ½ * (7 inches + 12 inches) * 4 inches
= ½ * 19 inches * 4 inches
= 38 square inches.
Therefore, the area of trapezium ABCD is 38 square inches.
The probable question may be:
Use a formula to determine the area of trapezium ABCD?
AB = 7inch, BC=5inch and CD=12inch, perpendicular from two parallel sides AB and CD is 4 inches.
