Question

What will be the length of the diagonal of a rectangle of sides 6m and 8m?

Answer 1

By pytahgoras theorem,

${6}^{2} + {8}^{2} = {x}^{2}$
here x is the diagonal

so
${6}^{2} + {8}^{2} = {x}^{2} \\ 36 + 64 = {x}^{2} \\ 100 = {x}^{2} \\ x = \sqrt{100} \\ x = 10$
since diagonal of a rectangle are equal we have both diagonals as 10m

Answer 2

By Pythagoras Theorem, 

length² + breadth² = diagonal²

6² + 8² = diagonal²

36 + 64 = diagonal²

100 = diagonal²

√100 = diagonal

10 = diagonal 


i hope this will help you
