Answer:
length should be 7.7 meters (if not 7.7 then 7.6)
Explanation:
A=LW
(area equals length times width)
just plug in what you know...
we know the area (A) is 20 square meters
we know that the width (W) is 2.6 meters
20=L2.6
now divide 2.6 to get L by itself which will give you
7.69230769231 (rounded to the nearest tenth is 7.7)
you can check this by adding 5 to the width (since it says the length is 5 meters longer than the width) and see if you get the same answer
hope this helps !! :)))
