Start with the formula:
Area = a2
Don't forget: a2 = a × a (a squared).
Substitute the side length into the formula. In our example, a = 6.
Area = 6^2 = 6 × 6 = 36 cm2
Answer:
The area of the square with sides of length 6 cm is 36 cm2.

Dividing both sides by 1.1, we get j = 5 ft. This was the height of the previous jump.
That is a 30 60 90 triangle.
