Applying the Pythagorean Theorem

Find the lengths of the two sidewalks


Step 1

square section

D=√{15²+15²}

D=√450 m

D=21.21 m


Step 2

rectangular section

D=√{15²+8²}

D=√289 m

D=17 m


Step 3

the sum of the lengths of the diagonals of the two sections is

17m + 21.21 m = 38.21 m


the answer is

38.2 m
