Problema Solution
The length of a rectangular field is 40 ft higher than its width. If the perimeter of the field is 784 ft, what is its length?
Answer provided by our tutors
Let 'l' and 'w' stand for the length and width. We can write:
l=w+40
2l+2w=784
Using Algebrator to solve for 'l' and 'w', we get:
l=216
w=176
