The length of a rectangle is twice as long as the width. The area is 200 ft2. What is the the length and the width of the rectangle.

The width is 10 ft and the length is 20 ft

Step-by-step explanation:

w = width

l = 2w

A = l*w

200 = lw

        = (2w) *w

200 = 2w^2

Divide each side by 2

200/2 = 2w^2   /2

100 = w^2

Take the square root of each side

sqrt(100) = sqrt( w^2)

10 = w

l =2w = 2(10) = 20

The width is 10 ft and the length is 20 ft

Width = 10ft

Length = 20ft

Step-by-step explanation:

Width = W

Length = 2W

Area = Length * Width

Substitute in known values

200 = 2W * W

200 = 2W²

Divide both sides of the equation by 2

100 = W²

Find the square root of 100

W = 10

Width = 10ft

Length = 2 * 10 = 20ft

Hope this helps :)

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
