Question :
What is the length of the red diagonal in the box? Express your answer to the nearest tenth of a millimetre.
Answer :
a2 + b2 = c2
7 squared + 12 squared = c2
( 7 x 7 ) + (12 x 12 ) = c2
49 + 144 = c2
193 = c2
square root of 193 = square root of c2
13.9 mm = c2
a2 + b2 = c2
5 squared + 13.9 squared = c2
( 5 x 5 ) + ( 13.9 x 13.9 ) = c2
25 + 193.2 = c2
218.2 = c2
square root of 218.2 = square root of c2
14.8 mm = c2
The length of the red diagonal box is 14.8 mm .

I think you should have explained what the equation did. Like the green equation measured the bottom hypotenuse and purple one measured the A&B after you figured out the hypotenuse.
Hey Jeric, your scribepost was awesome! I like how you used lots of colors but I really like how you got the answer and how you got it right. If you add some pictures and explain how you got your answers it would be even better. Overall you did great!
