The Length of a rectangle is twice the with the area of the rectangle is 90 square units know that you can divide the rectangle into two squares which number represents the length of each side of the Squares

2√45units

Step-by-step explanation:

Area of the rectangle = Length × Width

A = LW

If the Length of a rectangle is twice the width, then;

L = 2W

A = 2W(W)

Since area = 90

90 = 2W²

W² = 45

W = √45

Get the length

L =2W

L = 2√45 units

Hence the length of square is 2√45units

good luck on your studies! : )
