Answer:
61.37
Step-by-step explanation:
this is i believe the correct answer but i could still be wrong cause x times x is x square but i am not so sure how much that really matters
take x as the width
x plus 10 as the length
2x plus 10 equals 7544 squared
so square root 7544 minus 10 divided by 2
note that it must be done all at once u cant do it seperately
x is 61.37 dont forget to add 10
