a rectangle is 5 meter longer than what its width is. if the perimeter of the triangle is 30 meter, calculate the length and the breadth.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

L + W = 15,     (1)   (15 = 30%2F2)
L - W =  5.     (2)

Add and find the length L.

Then find the width W from any of (1), (2).

Answer. L = 10, W = 5.
