Question

WILL GIVE MEDAL
Half the perimeter of a building is 100 ft. The length of the building is 20 ft. more than the width. Find the dimensions of the building. (What are the 2 equations and how do I solve it?) Plss help!

Answer 1

100(2) = 200 = Perimeter.
20+w = length; w = width
20+w + 20+w + w + w = 200

Answer 2

Add like terms.

Answer 3

@Sadworld so the dimensions are only "length and width"?

Answer 4

Yes, for the perimeter.

Answer 5

Wait, misread.

Answer 6

For perimeter, you have 2l+2w=P. In this case they are telling you that L=w+20. So, if you substitute those into the equation, now you have 2(w+20)+2(w). Now, distribute.

Answer 7

Does that make sense @eunalexis ?

Answer 8

w(l)(h) = Dimension

Answer 9

But it's in prism form. Do i have to add height?

Answer 10

No, perimeter is only around the building, width and length. This can give another example, http://www.algebra.com/algebra/homework/conversion/Reduction-of-unit-multipliers.faq.question.209776.html

Answer 11

They don't do it fully, but they show how to set up the equation.

Answer 12

Thank you! :D @sleepyjess

Answer 13

No problem! Do you have to solve it completely?

Answer 14

Yes @sleepyjess

Answer 15

Ok, so now that we have the equation, we need to distribute. Can you do that?

Answer 16

Yep! Thank you! @sleepyjess

Answer 17

Would you like me to finish it with you or do you have it from here?

Answer 18

I can do it from here :) @sleepyjess

Answer 19

Ok :)
