Question

The sides of a rectangular field are 80m and 18m. Find the length of the diagonal.

Answer 1

Step-by-step explanation:

we know that

length of a diagonal of rectangle is

$\sqrt{a {}^{2} + b {}^{2} }$

=

$\sqrt{80 {}^{2} + 18 {}^{2} }$

=82 cm

hope it helps you..

Answer 2

The sides of a rectangular field are 80m and 18m. Find the length of the diagonal.

Length= $80m$

Breadth=$18m$

Diagonal= $?$

As the one angle of the triangle formed by the length, breadth and diagonal is 90  so, we can use the pythagoras theorem  to find the diagonal.

$d^{2}= 80^{2} + 18^{2}$

$d^{2}=6724$

$d=82m$

So, the length of the diagonal is $82m$.
