The required length of the diagonal of rectangle is a[tex]\sqrt{5}[/tex] .
let the width of rectangle = a
Length of the rectangle is twice of its width.
length = 2a
The rectangle is 4 sided geometric shapes whose opposites are equal in lengths and all angles are about 90°.
The required length of the diagonal
=[tex]\sqrt{length^2 + width^2}[/tex]
= [tex]\sqrt{(2a)^2+a^2}[/tex]
=√5a²
=a√5
Thus, the required length of the diagonal of rectangle is a[tex]\sqrt{5}[/tex]
