Explanation:

45 x 45 - 36 x 36 = 729 the square root of 729 is 27

Answer 2

a = 27 m is the answer.

Explanation:

a = ?

b = 36 m

c = 45 m

According to the Pythagoras theorem,

a² + b² = c²

a² + 36² = 45²

a² + 1296 = 2025

a² = 2025 - 1296

a² = 729

a = 27 m

∴ a = 27 m is the length of the missing leg.
