Question

Solve for c I need answers bad please

Answer 1

c=√45

Explanation:

I'm assuming this question is before Pythagorean theorem so.

1. Find the total area of the big square.
2. Find the total area of the four right-angled triangles.
3. Subtract the big square with the four right-angled triangles to find the area of the smaller square with sides 'c'.
4. Lastly, square root (√) the value to find c. Because c²=area of smaller square.

Big square area:

`(3 + 6) * (3 + 6) = 81`

All four right-angled triangles area:

`4( (1)/(2) * 3 * 6) = 36`

Smaller square area:

`81 - 36 = 45`

Value of c:

`{c}^(2) = 45 \\ c = √(45)`

Answer 2

c = sqroot45

Put a 45 in the box under the square root.

Explanation:

Use Pythagorean Theorem. See image.

Also, sqroot45 can be simplified. It 3root5, just in case they ask that next.
