Answer :
Answer:
Part 1) [tex]A=12.25\ m^2[/tex]
Part 2) [tex]P=14\ m[/tex]
Step-by-step explanation:
The question in English is
A carpenter will cut plywood measuring 3.5 meters x 3.5 meters. Determine the area and perimeter of the plywood.
Part 1) Determine the area
we know that
The area of a square is given by the formula
[tex]A=b^2[/tex]
where
b is the length side
we have
[tex]b=3.5\ m[/tex]
substitute
[tex]A=3.5^2=12.25\ m^2[/tex]
Part 2) Determine the perimeter
we know that
The perimeter of a square is given by the formula
[tex]P=4b[/tex]
where
b is the length side
we have
[tex]b=3.5\ m[/tex]
substitute
[tex]P=4(3.5)=14\ m[/tex]
