Jaelyn Salinas · Answer 1

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

Anabella Walker · Answer 2

Y = width of rectangle

2y = length

2 (L+W) = perimeter

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

Answer: 72cm^2
