Step-by-step explanation:
<u>First Table</u>
Length=10 feet, Width=4 feet
Area =10 X 4=40 Square Feet
<u>Second Table</u>
The second table is half as long as the first table.
Length =0.5 X 10 =5 feet
Area=5 X Width= 5w
The area of the second table is one fourth the area of the first table.

DerKrebs [107]
Evaluate the expression
where m=5 and n=4
We replace the value of m and n to evaluate
m=5 and n=4
50 + 4 = 54
The value of the given expression is 54 when m=5 and n= 4
