Answer: 23 in
Step-by-Step Explanation:
Height (h) = 18 in
Base (b) = ?
Area (A) = 207 sq. in
We know,
Area of a Triangle = 1/2 * b * h
Therefore,
1/2 * b * h = 207
1/2 * b * 18 = 207
b * 9 = 207
9b = 207
b = 207/9
=> b = 23
Base (b) = 23 in

3
Step-by-step explanation:
These are similar triangle
We can use ratios to solve
12 12+4
------ = ----------
9 9+DC
Using cross products
12( 9+DC) = 9*(12+4)
12 (9+DC) = 9*16
Divide each side by 12
12/12 (9+DC) = 9*16/12
9+DC = 12
Subtract 9 from each side
9+DC-9 =12-9
DC =3
