Hello There!
The length of the hypotenuse is 10.
We know what 2 sides are 6 and 8.
To find the third side we use the formula a^2 + b^2 = c^2
So we multiply 6 by 6 which equals 36 and then multiply 8 by 8 which equals 64.
Next we add 64 and 36 together and we get 100.
Next, we square root 100 and get 10.
10 is the length of the hypotenuse.
Since the <span>sides of a square aretwo to the power of four ninths inches long.

Therefore, it can be written as :
The side of the square =

Now, area of square = (side)*(side) =
Area, A =

or A =
Answer:
SA = 270 cm²
