Answer:
The area of a rectangle is given by:
(Area)=(length)*(width)
A=L*W
In this case, we know the area, and we know the relationship between length and width:
A=56 units1
W=L-10
We can substitute this information into the original equation for area:
A=L*W
(56 units1)=L*W [substituting the given area for A]
(56 units1)=L*(L-10) [substituting the given relationship between length and width]
Step-by-step explanation:
