The length of a rectangle is twice it width. The perimeter of the rectangle is 36cm. Calculate the area of the circle.

72cm^2

Step-By-Step Explanation

36=2(y+2y)

36=2(3y)

36=6y

y=6cm

Width of rectangle= 6cm

Length of rectangle= 2y=2×6 = 12

Area of rectangle= L×W = 12×6 =72cm^2

0 is its x and y coordinate

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
