Question 437569: I need to find the width and length of a billboard. the perimeter is 124ft. and the length is 6ft more than three times the width.
I understand that p= 124
and I need W2(?) + L2(?) = P that will equal 124ft.
but having the wording 6ft more than three times is were Im lost. Found 2 solutions by Klaus, scott8148:Answer by Klaus(2) (Show Source):
You can put this solution on YOUR website! your getting lost at writing the equation as the length is 6ft more than three times the width is the key to solving this problem.
The perimeter of a rectangle is 2(W)+ 2(L), we are giving perimeter so we can write our first equation...2(W)+2(L0=124
next write out the second equation which is the sentence your stuck at....... L=3(W)+6
so putting the 2 equations together to get 1 variable we get:
2(W) + 2(3W+6)=124
solve for W=14
solve for L=3 times width add 6
= 3*14+6
L = 48
hope that helps!
