Hi please answer this this and is not nesscary to show working but if you can is okay

Step-by-step explanation:

radius of circle = r inches

Width of the rectangle  = radius of circle = r inches

length of the rectangle = diameter of circle = 2r inches

Area of rectangle = 200 in^2

length * width = 200

2r * r = 200

r² = 200/2

r² = 100 = 10*10

r = 10 in

Radius = 10 inches

d

step-by-step explanation:

d

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
