Answer:
W perimeter = 40
Explanation:
All the sides of the squares equal the same amount.
If the perimeter of R is 28 divide 28 by 4 to give you 7.
And to get the area of a square you do length x width
So T would be 3 x 3 = 9
And it you add up 7 + 3 the sides on R and T = 10
So the left side on square W = 10
To get the perimeter multiply 10*4 = 40
I'm 90% sure, but hope this helps!!!
