Answer:
concept used
Here the concept of Perimetre and area is used. The radius of the circle is given as 7 metre. We will find the circumference of the circle.
circumference of the circle= perimetre of the square.
After equating the perimeters of circle and square we will get the measure of each side of square.
then, will find the area of the square
Formula used
Solution
Radius = 7 m
we know that
Therefore the side of square is 11 m.
Therefore the area of square is 121 m²
