calculate the area of the irregular polygon shown below:

Answer:
26 in²
Step-by-step explanation:
If we consider the outside rectangle, then subtract the 2 congruent white rectangles.
Area of outside rectangle = 10 × 5 = 50 in²
Area of 2 white rectangles = 2 × 4 × 3 = 24 in²
Thus the area of the E shape = 50 - 24 = 26 in²
