Answer:
a) C x +x +x +3x +3x = 18
b) x = 2
c) 2 cm, 6 cm
Step-by-step explanation:
a) The sum of the lengths of the sides is equal to the length of the perimeter. The appropriate equation is ...
x +x +x +3x +3x = 18
__
b) Simplifying, the equation becomes ...
9x = 18
x = 2 . . . . . divide by 9
__
c) The shorter sides are x = 2 cm.
The longer sides are 3x = 6 cm.
