Answer:139 cm squared
Step-by-step explanation:
First separate it:
10x3
7x7
4x15
These are the 3 rectangles that make up this shape
Then multiply
10x3=30
7x7=49
4x15=60
Then add your answers
30+49+60=139cm squared
When you have two squares stacked on top of each other, pretend the angle in the bottom left of the top square is a 90 degree angle, that means that the angle of the square right underneath, also sharing the line, is a 90 degree angle. Or whatever you would need to get it equal to 180, my example was 90/90.
