The perimeter of Jonah's square backyard is 56 meters. What is the area of Jonah's backyard?
2 answers:
Answer:
area of Jonah's backyard is, 196 meter square
Step-by-step explanation:
Perimeter(P) of square is given by:
where a is the side of thew square
As per the statement:
The perimeter of Jonah's square backyard is 56 meters
⇒
Using the perimeter formula to solve for a:
Divide both sides by 4 we have;
or
a = 14 m
Area of a square(A) is given by:
Substitute the given value of a = 14 m to get area;
Therefore, the the area of Jonah's backyard is, 196 meter square
