Answer: x*(x-5)
Step-by-step explanation:
Plexiglass is a cuboid
which means that the area would be l*w
in the question it states that the width is 5 cm shorter than the length
since we dont know the values
we represent them as x
so using l*w
we write x*(x-5)
Since a yard is 3 feet, then 3 times 3 is 9 and that is less than 21.
You have nice hand writing :)
