The circumference of a rectangle is equal to that of a circle. The length of a rectangle is 4.85cm, which is 1.85cm longer than the width. What is the area of the circle in square centimeter?

The circumference of a rectangle is equal to that of a circle. The length of a rectangle is 4.85cm, which is 1.85cm longer than the width. What is the area of the circle in square centimeter?

（4.85+1.85）*2=13.4
13.4/3.14 /2=2.13
3.14 * 2.13 * 2.13 = 14.25 square centimeter

The rectangle is 12 decimeters long and 150 percent wide, with its perimeter and area

C=2(a+b)
=2*(12+12/1.5)
=40 decimeters
S=ab
=12*(12/1.5)
=96 square decimeters

The circumference of the rectangle is 12 cm, and its ratio of length to width is 4:3. How many cm are the length and width of the rectangle
Hurry up

If the length is 4x, the width is 3x
2(4x+3x)=12
7x=6
X = 6 / 7
It's 24 out of 7 in length and 18 out of 7 in width
Hope to adopt
