The dimensions of a rectangular field are 80 m and 18 m. Find the length of its diagonal.
Advertisements
Solution
Here, length of a rectangular field (l) = 80 m
And breadth of a rectangular field (b) = 18 m
∴ Length of diagonal = `sqrt(l^2 + b^2)`
= `sqrt((80)^2 + (18)^2`
= `sqrt(6400 + 324)`
= `sqrt(6724)`
= 82 m
