Help pls fast 15. In a parallelogram ABCD, AB = 7.2 cm and the perpendicular from C on AB is 4.5 cm find its area.

32.4 cm²

Step-by-step explanation:

Given the parallelogram ABCD ; with AB = 7.2 cm

Perpendicular from C on AB is the height of the parallelogram = 4.5 cm

Using the relation fir the area of a parallelogram :

Area of a parallelogram = base * height

Area of a parallelogram = 7.2 cm * 4.5cm

Area of parallelogram = 32.40cm²

Hence, Area of parallelogram is 32.4 cm²

the square root of what number? if you add that, then someone will probably answer the question.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.
