Question

Can anyone explain how to do this?

Answer 1

Answer:

85 units²

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

The hypotenuse is the side opposite the right angle ( third side ) , then

area = 35 + 50 = 85 units²

Answer 2

Answer: 85 units ^2

Step-by-step explanation:

Using the equation $a^{2} + b^{2} = c^{2}$

so $a^{2} = 35$ and $b^{2} =50$

$a^{2} + b^{2} = 85^{2}$
