If the height of the parallelogram shown is increased by 1 cm and the base is increased by 2 cm, what is the area of the new parallelogram? A parallelogram with a base of 9 centimeters and a height of 4 centimeters. 28 cm2 39 cm2 55 cm2 60 cm2

Area = 55 cm2

Step-by-step explanation:

It the base of the parallelogram was 9 centimeters and increased by 2, the new base has 9 + 2 = 11 centimeters.

It the height of the parallelogram was 4 centimeters and increased by 1, the new base has 4 + 1 = 5 centimeters.

Now, we can calculate the area of the parallelogram using the formula:

A = b * h

Where A is the area, b is the base and h is the height. So:

A = 11 * 5 = 55 cm2
