I'm confused on finding the area of this question

7200 cm²

Step-by-step explanation:

You need to do two things before calculating the area:

1) All lengths must be in the same unit.

2) Divide the compound figure into two rectangles.

See the picture below.

Use the conversion 1 m = 100 cm to change the two lengths in m to cm.

2 m = 2 × 100 cm = 200 cm

4 m = 4 × 100 cm = 400 cm

area of rectangle = length × width

total area = 12 cm × 200 cm + 12 cm × 400 cm

total area = 2400 cm² + 4800 cm²

total area = 7200 cm²

your answer would be 10x - 1
