To find the area of this shape, start by splitting it into two rectangles, along the line that says “two units”.
The left rectangle now has two side lengths of 4, so it’s actually a square. This left rectangle has an area of 16 square units.
The right rectangle is five units long by two units high, as 9-4=5 (the longest side minus the length of the left square) and 4-2=2 (the left side of the shape minus the two units). This means that the right rectangle has an area of 5x2, or ten square units.
To get the total area, add up the areas for both shapes. This means that the total area is 16 + 10, or 26 square units.
