Answer:

222 yd²

Step-by-step explanation:

Bottom and top area, each = 7 * 3 = 21 yd²

Two lateral surdaces, each = 7 * 9 = 63 yd²

Two lateral surdaces, each = 3 * 9 = 27 yd²

Total area = 2 x (21 + 63 + 27) = 222 yd²

I just did this is our math book at school, but what you do is find the GCF of the numbers. So list all there factors. 27=1x27, 3x9, and that's it. 36=1x36, 2x18, 3x12, 4x9, and that's it. So, next you see that highest numbers they both have in common, in this case it is 9. So your answer is, 9 pansies.
