Six rectangles each with a common base width of 2 have lengths of 1,4,9,16,25, and 36. What is the sum of the areas of the six rectangles?

Sagot :

Area of Rectangle = Width x Length

Equation:
Sum of the areas = 2 (1 + 4 + 9 + 16 + 25 + 36)
                          = 2 (91)
                          = 182 sq. units
                          
The sum of the areas of the 6 overlapping triangles is 182 sq. units.

182 sq. units.

I don't think that this is middle school math. I learned this in 3rd grade.
