My first Scheme program

I’ve just started experimenting with Scheme, specifically to follow Structure and Interpretation of Computer Programs. Here is a Scheme procedure that returns the sum of squares of two larger numbers out of the given three.

(define (sumLargeSquare a b c)
  (cond ((and (< a b) (< a c)) (+ (* b b) (* c c)))
        ((and (< b a) (< b c)) (+ (* a a) (* c c)))
        (else (+ (* a a) (* b b))))
