Explanation:

Step1: Find square side from area

For a square, $s = \sqrt{\text{Area}}$

O: $s = \sqrt{25} = 5$ m

I: $s = \sqrt{64} = 8$ cm

E: $s = \sqrt{400} = 20$ ft

Step2: Calculate square roots

S: $\sqrt{49} = 7$

L: $\sqrt{16} = 4$

I: $\sqrt{100} = 10$

O: $\sqrt{81} = 9$

E: $\sqrt{36} = 6$

D: $\sqrt{4} = 2$

H: $\sqrt{144} = 12$

N: $\sqrt{1} = 1$

C: $\sqrt{900} = 30$

H: $\sqrt{2500} = 50$

U: $\sqrt{6400} = 80$

D: $\sqrt{10000} = 100$

Step3: Simplify expressions

E: $15^2 = 15 \times 15 = 225$

H: $11^2 = 11 \times 11 = 121$

A: $25^2 = 25 \times 25 = 625$

E: $\sqrt{121} = 11$

L: $\sqrt{625} = 25$

A: $\sqrt{16} + \sqrt{9} = 4 + 3 = 7$

E: $\sqrt{36} + \sqrt{64} = 6 + 8 = 14$

R: $\sqrt{25} - \sqrt{9} = 5 - 3 = 2$

N: $\sqrt{16+9} = \sqrt{25} = 5$

T: $\sqrt{36+64} = \sqrt{100} = 10$

L: $\sqrt{0.25} = 0.5$

B: $\sqrt{0.81} = 0.9$

J: $\sqrt{0.01} = 0.1$

Step4: Match letters to answer boxes

Part I/II Box Matches:

5: O; 8: I; 20: E; 7: S; 4: L; 10: I; 9: O; 6: E; 2: D; 12: H; 1: N; 30: C; 50: H; 80: U; 100: D

Part III Box Matches:

225: E; 121: H; 625: A; 11: E; 25: L; 7: A; 14: E; 2: R; 5: N; 10: T; 0.5: L; 0.9: B; 0.1: J

Final Letter Sequence (reading answer boxes left to right):

Part I/II: S, O, I, D, L, O, I, E, H, N, E, C, H, U, D

Part III: A, T, H, E, L, E, P, H, A, N, T, W, A, N, T, E, D, T, O, M, A, K, E, H, I, S, F, E, E, T, L, O, O, K, L, I, K, E, A, R, A, I, N, B, O, W
