Explanation:
To find the area of the square all you need to do is to find the length of the hypotenuse of the triangles
this will help us find the length of the square if we are given the values of the shorter lengths as shown up
we can calculate the length of the hypotenuse by using the Pythagorean theorem

we are given the sides of the shorter lengths being 5 and 3 we can then substitute them into the formula
let us label the missing length the hypotenuse as x



we get that 5.83 rounded to two decimal places is the length of the hypotenuse
we also know that it is the length of the square so
5.83 × 5.83 = Area of Square
34cm² = Area of Square
