Calculate the area of the shaded region when x=30 cm

Answer:
836
Step-by-step explanation:
So we know x = 30, which means to find the area you just do 30 x 30 which equals 900 (perimeter is when you add it all).
We also know that each square has an area of 16, because we're given one side length, and the ticks in the middle of each line means they are congruent, which means that they are equal to each other.
So now we can multiply 16 by 4 because there are 4 squares. 16 x 4 = 64
Now, we just subtract 64 from 900. 900 - 64 = 836
