Triangle area = 8 x 3/2
= 12
12 x 2 = 24cm^2 for 2 triangles
Height of rectangle must be found, so use pythag on triangle
a^2+ b^2 = c^2
16 + 9 =c^2
C=5
A= 5 x 12
= 60
60 x 3 triangles in total is 180cm^2
180cm^2 + 24cm^2 = 204cm^2
Ans: 204cm^2
The answer will be a because they are similar and by law the ratio can be cubed to find ratio of volume
Answer:
We have 4 x ( 3 / 2 ) = 12 / 2 = 6;
