Hello, monkius!

1.A right triangle has an area of 25 cm².

Express the hypotenuse, , of this triangle as a function of its perimeter,Code:* | * h b | * | * * - - - - - * a

The area is 25 cm²: .

The perimeter is: . .[1]

Square both sides of equation [1]: .

And we have: .

. . or: .

So we have: .

Therefore: .
