Question

In a parallelogram, a base b, and its corresponding height, h, are in the ratio of 5:3. The area is 135 mm squared. Find b and h.

Answer 1

Since you have this ratio, you have:

b/h = 5/3 which is b = 5h/3

Your area is b x h = 135

Substituting:

(5h/3)(h) = 135 -> (5h^2)/3 = 135

Now, try solving for "h". Once you do that, you can use the original ratio to get "b".

Thx for the recognition! @ajprincess

Answer 3

How is this going for you, @samanthablank ?

Answer 4

u r welcome:) nd u really deserv it:)

Answer 5

Those are worthy, kind words indeed. Especially coming from a 99'er.

Answer 6

5h^2/ 3 = 135/1
5h^2=405
divide both sides by 5:
h^2=81
square toot both sides:
h=9

did I do that right?
and now, I would just plug h into the ratios, right?

Answer 7

You are doing very well here! Keep up the good work! Yes, just plug into the ratio now.

Answer 8

ok, thanks! :)
