Can you recheck this hopefully this time i did it correctly.

Directions:
Crafts. Rose's garden is in the shape of a trapezoid. If the height of the trapezoid is 16m, one base is 12m, and the area is 224m ^2, find the length of the other base.

My answer:
224 = 1/2h (B1 +B2)
224 = (1/2)16(20 + b2)
224 = 8(20 + b2)
224 = 160 + 8b2
-160 -160
64 = 8b2
-- ---
8 8

8 = b2

My answer:
224 = 1/2h (B1 +B2)
224 = (1/2)16(20 + b2) Isn't b1 12 and not 20?
224 = 8(20 + b2)
224 = 160 + 8b2
-160 -160
64 = 8b2
-- ---
8 8

8 = b2
Your math is ok and you came out with the correct answer IF B1 is 20 But the problem said 12. I found 16 for B2.

Sorry that was a typo. But is everything okay the format.

looks ok to me.
