Question

I need help with this problem

Answer 1

Answer:

h = 15

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:

$12h=(18)(10)$

$12h=180$            divide both sides by 12

$h=15$
