The figure is composed of a rectangle of width \( w \) and height \( h \), and a right triangle with base \( b \) and height \( h \) attached to its side.
Enter a formula for the total area in terms of \( w, h, b \).
Correct Answer
$A = wh + \tfrac12 bh$
Explanation
Area of rectangle is \( wh \). Area of right triangle is \( \tfrac12 bh \). Total area is their sum.
