Need help with these question! Thank you!

Answer:
a) 11 inches
b) 9 m
Step-by-step explanation:
Using the appropriate formulas for area, fill in the given information and solve for the variable that remains.
a) A = 1/2·b·h
82.5 = 1/2·15·h
h = 82.5/7.5 = 11 . . . . . divide by the coefficient of h
The height is 11 inches.
__
b) A = b·h
65.7 = 7.3b
b = 65.7/7.3 = 9 . . . . . divide by the coefficient of b
The base is 9 meters.
