What is the order of this matrix?
14 1 - 2
3-5 1
3 6 il
L3 i 0 ]
A. 2x3
2
B. 3* 5
OC. 563
D. 3 * 2

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square
