Question

Find the area of the composite figure.

Square with missing top corner.


12in prarel to 10in

top 14in
bottom 20in.

All of little boxes on the three showm corners.

I did this.

Find area of rectangle

A= lxw
14 x 12 = 168 in.


Find triangle area

A = 1/2 x b xh
A= 1/2 x 12 x 10 = 60 in.


168+60 = 228 in squared


Where am I wrong? I think the rectangle is right, but not the triangle.

The correct answer is 234 in squared but I don't know how ?

Answer 3

So, is 234 right or 228?
