Symmetry signifies balance and form. An object with

length of the diagonals, the angles of each corner, or parallelism of opposite
sides will remain the same.
I answered this using trial and error, so let me know if you need workings, but I got the dimensions as 18 inches and 13 inches.
I hope this helps!
2(2/5+1/5)=2•3/5=6/5=1 1/5
Answer is C
<h2>For the number 1<u>.</u><u>.</u></h2>
<h2><u>angle </u><u>at </u><u>center </u><u>=</u><u> </u><u>2</u><u>×</u><u>a</u><u>n</u><u>g</u><u>l</u><u>e</u><u> </u><u>at </u><u>circumference</u></h2><h2><u>the </u><u>angle </u><u>at </u><u>center </u><u>(</u><u>o)</u><u> </u><u>is </u><u>equal</u><u> </u><u>to</u><u> </u><u>1</u><u>4</u><u>1</u></h2>
<u>therefore:</u>
