we start by calculating the value of x

152=x2+x215^2=x^2+x^2

225=2x2225=2x^2

225/2=x2225/2=x^2

112.5=x2112.5=x^2

112.5=x2\sqrt{112.5}= \sqrt{x^2}

10.61=x10.61=x

length x= 10.61m

next we find the diagonal D

length = 50x=5010.61=39.3950-x=50-10.61=39.39

width =40x=4010.61=29.3940-x=40-10.61=29.39

D=39.392+29.392\sqrt{39.39^2+29.39^2}

D=49.1549.15

area of the road =15D15*D

=1549.1515*49.15

=737.25m2737.25m^2
