Answer:
Correct answer is (10)
Explanation:
since 2 triangles come together to form a square\rectangle
length * width = Area
we can find both areas of the triangles:
left triangle: 2*2 = 4 --> 4 devided in half = 2
square area = 4
right side triangle: 2*4 = 8 ---> devided in half = 4
______________________________________
next add up all the measurements for each piece:
left triangle + middle square + right side triangle = area
(2+4+4 = 10)
Hope I helped you out :)
Have a great day \ and good luck on your studies :D
