The width of a rectangular park is 36 feet and its diagonal footpath is of length 85 feet find the length of the rectangular park

Academic Mathematics NCERT Class 7

Width =36 feet

Diagonal =85 feet

The width, length and diagonal form a right angled triangle

Diagonal²=Width ²+Length²

=>85²=36²+Length²

=>85²-36²= Length²

=>7225-1296=Length²

=>5929=Length²

=>√5929 = Length

=>77=Length
