The length of a rectangle is twice the width The area of the rectangle is 90 square units.
note that you can divide the rectangle into

which irrational number represents the length

Step-by-step explanation:

Area of a reactangle = Length * Width

A = LW

If the length of a rectangle is twice the width, then L = 2W

Substituting L = 2W into the formula for calculating the area

A = 2W(W)

A = 2W²

Given the area of the rectangle to be 90 square units, then;

90 =  2W²

2W² = 90

divide both sides by 2

2W²/2 = 90/2

W² = 45

W = √45

To get the length of the rectangle, we will substitute, W = √45 into L = 2W

L =2√45

L = 2√9*5

L = 2(3)√5

L = 6√5 units

Hence the irrational number that represents the length is 6√5 units.
