Answer 2

Step-by-step explanation:

QUESTION:

Find the length of the side of a square whose area is 441 m².

GIVEN:

Area of square = 441m²

SOLUTION:

Area of square = 441m²

therefore,

$length \: of \: the \: side \: of \: the \: square \: = \sqrt{area \: of \: square} \\ = \sqrt{441 {m}^{2} } \\ = \sqrt{21 \times 21 \times m \times m} \\ = 21m$

ANSWER: Length of each side of the square is 21m.
