Answer:
Explanation:
Ok so let us take it step by step and divide it into 3 parts
The leftmost part, the bottom part, and the rightmost part.
So this is basically a rectangle with a big chunk taken out of it.
We know the perimeters of the chunk because the Width is given and the Length is basically the total length of the bottom line and the 2+2 from the above one. So we know L=4 and W=3 which is 12
Now we find out the area of the rectangle which is 4*10=40
And 40-12=28 and 28 is the answer
