What is the area in square millimeters of the triangle outlined
on the origami figure?

HELP

44.1 mm^2

Explanation:
The formula to find the area of a triangle is A=bh/2 (this is the area of a square divided in half because 2 triangles make a square). Given b=7 cm and h=1.26 cm, plug the numbers into the formula:
A=bh/2
A=(7*1.26)/2
A=8.82/2
A= 4.41 cm^2
The question asks for the area in square millimeters. Centimeters to millimeters is found by a division of 10, moving the decimal to the right by one place. So, the answer is 44.1 mm^2.
