Homework Help: algebra/math

Posted by Mike 50 on Wednesday, March 11, 2009 at 1:45pm.

I have this figure of a square QRST with an equilateral triangle PQT sitting on top of the square. The figure looks like a little house...

My question is if PQ equals 6 cm, then what is the area of the square?

Do I need to find the area of the triangle to figure this out? Do I use 1/2(B)(H) to find area of triangle and do I use a2 to find area of square....Please help

If the triangle is equalaterial, then QT is also six, so the area of the square is 36.
