The length and width of the rectangle is 2√5m and √5m respectively
<h3>Volume of a rectangle</h3>
The formula for calculating the volume of a rectangle is expressed as:
V = lw
where
l is the length
w is the width
h is the height
If base is twice its width, then l = 2w
Substitute
10 = w(2w)
10 = 2w²
5 = w²
w = √5 m
Since l = 2w
l = 2√5m
Hence the length and width of the rectangle is 2√5m and √5m respectively
