A sheet of paper measures 12 cm by 15 cm. Vince cuts the paper from one corner to the opposite corner,
making two congruent triangles. What is the area of one of the triangles?
Explanation: If the whole paper is 12 by 15 you have to divide them both by 2! 12 divide by 2=6 15 divide by 2=7.5 Then you have to multiply them together to find the area. 6x7.5=45 So therefore the answer is 45cm.
