NUMBER C EQUATION

if the answer equals 600mm squared you can use that to work out the rest of your answer. I used my mind to create an answer that would match e.g. Each bass length is 30mm long and each height length is 20mm long. And with that I multiplied 20 by 30 and it gave me the answer of 600mm squared.
