Question

Clearly i am doing something wrong after multiplying the numbers together i got 8,064 what did i do wrong

Answer 1

12 x 6 + 8 x 8 = ?

or

4 x 6 + 8 x 14 = ?

Answer 2

Multiplying length times width will only result in the area of the shape if it is a rectangle or square.

The key here is to "cut" the shape into two rectangles, then find the area of those two rectangles individually and add them together.

Try to find a way to cut the shape into a 14 ft x 8 ft rectangle and a 6 x 4 ft rectangle.
