I need help with this problem
Dmitriy789 [7]

Answer:

<h2>h = 15</h2>

Step-by-step explanation:

The formula of an area of a parallelogram:

A=bh

b - side

h - height

We have b₁ = 18 and h₁ 10 and b₂ = 12.

b_1h_1=b_2h

Substitute:

12h=(18)(10)

12h=180            <em>divide both sides by 12</em>

h=15
