Width = 10cm
Length = 25cm
<u>Explanation:
</u>
Given, width:length = 2:5
Let width = 2x ,
So, length = 5x
Perimeter of rectangle = 2x(length + width)
According to the question,

Hence,
Width = 10cm
Length = 25cm
Since all the angles are the same measure, each angle has to be equal to 60 since all three angles add up to 180. YOU'RE WELCOME :D
