pleas exxplain the full formula for me so i can uderstand this

OpenStudy (mathstudent55):

There is no single formula that can find the area of the complete figure. Instead, you break up the figure into parts with known shapes and you find each area. Then you add the areas together.

Good. Look in the original figure of your problem. What are the length and width of the rectangle?

22 x 17?

OpenStudy (mathstudent55):

Correct. Now multiply them together to find the area of the rectangle.

374

OpenStudy (mathstudent55):

Correct. 22 cm * 17 cm = 374 cm^2
