Triangle is cut out of a square whose side length is 12 feet what will be the approximate area in square feet of the remaining board

I think the answer would be 72ft^2 if this is all the information given.

Explanation:

You can cut a square from corner to corner and get 2 triangles. Therefore a square has the area of 2 times a triangle.

So you first find out the area of the square which is 144 because it has a side length of 12

(Lenghtxwidth=area)
