Problema Solution
A large movie screen is in the Panasonic IMAx theater at DArling HArbor, Sydney,Australia. The rectangular screen has an area of 11,349 square feet. Find the dimensions of the screen if it is 20 feet longer than it is wide.
Answer provided by our tutors
the width is 664.5 and the length is 684.5
area= length x height
1349= w x w+20 where w = width
subtract 20 from both sides leaves
1329 = 2w
divide both sides by 2
664.5= w
now we have the width
664.5 + 20 = L
so the width is 664.5 and the length is 684.5
