Hello!
1 m = 100 cm
That means that 3 m = 300 cm, and 4 m = 400 cm.
Now that we know what the base and height are in cm, we must use the formula for area of a parallelogram to find the area:
FORMULA:
A = bh
SUBSTITUTE:
A = 400 × 300
A = 120,000
The area the parallelogram is 120,000 square cm.
(Put a small 2 above cm, instead of writing 'Square').
