Question

Find the approximate side length of a square game board with an area of 149 in. squared.

Answer 1

→ Formula:

`{ \tt{area = side * side}}`

• substitute for the area:

`{ \tt{149 = {s}^(2) }} \\ { \tt{ {s}^(2) = 149 }}`

• take square roots on either sides:

`{ \tt{ \sqrt{ {s}^(2) } = √(149) }} \\ \\ → \: { \boxed{ \tt{side \: length \approx12 \: inches}}}`
