Step-by-step explanation:
The square has 4 sides with length 4
The right triangle has the right side equal to 4yd + 4yd(from the square) = 8yd
Using the Pythagorean Theorem, we find that the left side of the triangle has length = 10yd
The area of the whole thing is the area of the square + the area of the triangle
The formula for the area of a square with sides <em>l</em> is
The area of the triangle is trickier, but you can imagine tracing a line in the left side and the upper side to form a rectangle, and the area of that is A = , the area of the triangle will be half the area of the rectangle so it'll be
The total area will be;
Area of the square + Area of the triangle =
