I believe the answer is D, but I might be wrong.
Answer:
Step-by-step explanation:
Alright, lets get started.
The surface area of the figure given is : The area of all shapes together
The figure has 2 similar triangles and 3 similar rectangles.
The area of 1 triangle =
The area of 1 triangle =
So, the area of both triangles =
The area of 1 rectangle =
The of 1 rectangle =
So, the area of all 3 rectangles =
So, total area of figure =
hence the surface area is 536.6 square centimeters : Answer
Hope it will help :)
Answer:
804,642
Step-by-step explanation:
800,000 + 4,000 + 600 + 40 + 2.
Add the terms
804,642
3 1/2 can be changed to 7/2 by doing 2 x 3+1
same thing with 1 3/5 can be changed to 8/5 by 5 x 1 +3
7/2 x 8/5 x 9/6
numerators: 7*8*9=504
denominators: 2*5*6=60
numerators/denominators= simplify to get final answer
504/60=8 24/60=8 2/5
