For each pair of Examples below, decide whether the two examples have the same contract. If they do, fill in the contract in the space provided. If not, write a few words explaining how you know their contracts aren’t the same.


examples: mystery​(​triangle​(​70, "solid", "green"​)​) is triangle​(​140, "solid", "green"​) mystery​(​circle​(​100, "solid", "blue"​)​) is circle​(​200, "solid", "blue"​) end


examples: mystery​(​"red"​) is triangle​(​140, "solid", "red"​) mystery​(​"blue", "circle"​) is circle​(​140, "solid", "blue"​) end


examples: mystery​(​"+", 4, 5​) is 4 + 5 mystery​(​"sqrt", 25​) is num-sqrt​(​25​) end


examples: mystery​(​"circle", 4​) is num-pi * num-sqr​(​4​) mystery​(​"square", 5​) is num-sqr​(​5​) end


examples: mystery​(​"dog"​) is 3 mystery​(​"cat"​) is "kitten" end


examples: mystery​(​"dog"​) is 3 mystery​(​"kitten"​) is 6 end
