Not enough information.
Are we supposed to know the geometrical shape of the wing?
Is is a rectangle?
Is it a trapezoid?
???
If it is a rectangle then you are correct, except your method of solving
is rather primitive. What is the area had been 174 ft^2 ?
The area of the wings of a small Cessna is 175 ft2. If the length is 30 ft longer than the width, what are the dimensions of the wings? (This wing is one piece and goes along the top of the aircraft.)
my answer:
175 feet and the length is 30 ft longer and I looked through all the possible multiplication factors of 175
1,5,7,25,35,175,
the answer is got are 5 and 35
is length is 35 and width is 5?
