l = 6 + 2a - 1
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = lw ( l is the length and w the width )
given A = 18 + 6a² - 3a and w = 3a , then
3aw = 18 + 6a² - 3a ( divide each term by 3a )
w = + - = 6 + 2a - 1
X=3
because a triangle with side length 3,4,5 is right angled
