Answer 1

Please type your <u>subject</u> in the <b>School Subject</b> box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.

Answer 2

first first the dimensions of the room ....

x(x+2) = 168
x^2 + 2x - 168 = 0
(x-12)(x+14) = 0

I am sure you can take it from here
