Answer:
58.06cm²
Step-by-step explanation:
It's a, square so all the sides are equal.
Using Pythagoras theorem we can find one side of the square.
a² = 7² + 3²
a² = 49 + 9
a² = 58
a = [tex]\sqrt{58}[/tex]
a = 7.615...(7.62 to the nearest 2 decimal place)
Area = 7.62 × 7.62
Area = 58.0644
∴ The area of the shaded square is 58.06cm²
