Question

The diagram shows a polygon. Find the area, in cm², of the whole diagram. ​

Answer 1

Answer:

168 $cm^{2}$

Step-by-step explanation:

Consider the picture, break it into a rectangle with a triangle on top.  Use the following equation to find the total area of the figure.

$A_{total}$ = $A_{rectangle} + A_{triangle}$

        = length×width + $\frac{1}{2} bh$

       =  (12cm)(10cm) + $\frac{1}{2}(12cm)(8cm)$

       = 120$cm^{2}$ + 48$cm^{2}$

       = 168$cm^{2}$

Answer 2

Answer:

Bottom part = 10 * 12 = 120 square centimeters

Top part 8 * 6 = 48 square centimeters

Total Area = 168 square centimeters
