Answer:

C). 54 cm.

Step-by-step explanation:

I think you mean a rectangle .

If the length is x then the width = 0.75x (because 3/4 = 0.75).

Perimeter = 2*length + 2*width.

252 = 2x + 2*0.75x

252 = 2x + 1.5x

252 = 3.5x

x = 252 / 3.5

= 72 which is the length,

The width = 3/4 * 72

= 54 cm.

So first simplify 11/6x into 11x/6. Then -13/10x into -13x/10. So you should now have (-13x/10-11x/4)-3/2. Combine the like terms -13x/10 and -11x/4 to get -81x/20 and then with your left over -3/2= -81x/20-3/2
