4/52 = 1/13 <== here ya go
Perimeter is adding all sides so the answer will be 12(pi) + 46, hope this helps!!
Answer: 360 square inches
Step-by-step explanation: calculate area by multiplying length by height
If the triangles are similar, the proportion of the legs on the left to the legs on the right will be equal. This proportion would look like:

(You needed to combine the orange segment and the yellow segment to find the total length of the large triangle).
Now, cross multiply and solve for x:
28x+14=30x
<em>*Subtract 28x from both sides to isolate the variable*</em>
14=2x
<em>*Divide both sides by 2*</em>
7=x
Hope this helps!!
