The length of a rectangle is twice as long as the width. The area is 200ft to the power of 2. Find the length and the width of t
zimovet [89]

Answer:

Length = 20feet

Width = 10feet

Step-by-step explanation:

Area of a rectangle = LW

Perimeter P= 2(L+W)

L is the length

W is the width

If the length of a rectangle is twice as long as the width, then;

L = 2W

Substitute into the foemula

A  = (2W)W

A=  2W²  

If the area is 200ft², then;

200 = 2W²

100 = W²

W = √100

W = 10ft

Since L = 2W

L = 2(10)

L = 20ft

Hence the length of the rectangle is 20feet and the Width is 10feet

What is the 1st term when 3x3 − 7x + 6x4 − 2x2 is arranged in descending order?
azamat
The correct option is 6 X 4.
To arrange in descending order means that you will write the largest value first followed by the other smaller ones. From the question given above, we have the following values:
3x3 = 9
6 x 4 = 24
-2 x 2 = -4 and we have  -7x.
Thus, the largest value is 6 x 4.
