Answer:
51 cm^2
Step-by-step explanation:
To find the area excluding the shaded triangle, first find the area of the whole figure:
12 x 6 = 72cm^2
Now, find the area of the triangle:
(7 x 6) / 2
42/2
21cm^2
Lastly, subtract the shaded area from the whole:
72 - 21 = 51 cm^2
42 sq. centimeters
6 x 7 = 42.
15.6
because 6×2.60
& =
~
-9/6
simple, multiply the 7/3 by 2 to get the same denominator, then just subtract
