A builder divides a rectangular plot in half along the diagonal.If the plot is 1\2-mile wde and the diagonal measures 1 3\10-miles long,what is the length of the plot?
*explanation* To Make 1 3/10 into an improper fraction you have to multiply the denominat times the whole number, 10x1 which equals ten. then you have to add the numerator to that (10+3=13) hope this helps!
