What is the area of this polygon?
A) 24 cm2
B) 16 cm2
C) 40 cm2
D) 18 cm2

Answers

Answer:

C) 40 cm²

Step-by-step explanation:

area of top triangle = 1/2 x 8 x 6 = 24 cm²

area of bottom triangle = 1/2 x 8 x 4 = 16 cm²

24 cm² + 16 cm² = 40 cm²

C would be the answer this is the correct answer because it makes most sense and also that’s correct because

The area of the top is :1/2x8x6=24 cm
Next!!

The area of the bottom is:1/2x8x4=16cm
Next!!
24 cm +16 cm = 40cm
Next!!
