Answer:

Step-by-step explanation:

Area A = 1/2 bh

36a^2b^4 = 1/2 × (12ab)h

Cross multiply

72a^2b^4 = 12abh

Dividing by 12ab

h = (72a^2b^4)/12ab

h = 6ab^3

A=1/2ab
Replace the variables with their value
15=1/2(3/2)b
Multiply 1/2 and 3/2
$\frac{1}{2} \times \frac{3}{2 } = \frac{3}{4}$
15=3/4b
Divide 3/4 on both sides
15/(3/4) is the same thing as
$\frac{15}{1 } \times \frac{3}{4} = \frac{45}{4}$
45/4=b
