Use formulae of rectangle.
The distance from a circle's center to a point on the circle is called the radius of the circle.
Area of rectangle = length × breadth
Area of square = side2
Perimter of rectangle = 2(l+b)
Perimeter = 30 ft
b= 5 ft
Area= = 50 sq ft
Take width as x.
perimeter= , we get side= 30 m
Area = side2 = 900 sq m
Area of parallelogram = base x height
Is this perimeter or area?
