Question

Can anyone explain how to do this?

Answer 1

85 units²

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

Explanation:

Using the equation
`a^(2) + b^(2) = c^(2)`

so
`a^(2) = 35` and
`b^(2) =50`

`a^(2) + b^(2) = 85^(2)`
