The width of a rectangle is 4 feet and the diagonal length of the rectangle is 13 feet. Which measurement is closer to the length of this rectangle in feet?
A. 12.4 ft
B 13. 6ft
C 9ft
D 17 ft
I’m not sure which answer this is
The answer you would be looking for is A.12.4 feet. You can use the equation A^2+b^2=c^2 to solve for your x being length. Making 4^2+b^2=13^2 or 16+b=169 Take 16 from both sides B=153 then square root both sides B^2 or x= 12.36 or 12.4 if you choose to round up as asked in the question. I hope this helps!
