Mathematics
1 answer:
Lubov Fominskaja [6]3 years ago
5 0

Answer:

27

Step-by-step explanation:

Since the total area is 243, we plug that in to the given equation and get 243=1/2(b)(h).

Then we plug in 18 to the height and get

243=1/2(b)(18)

Then solve for b

243/18=1/2(b)(18)/18

13.5=1/2(b)

13.5/1/2=1/2(b)/1/2

27=b
