Question

The length of a rectangle is 7 units and its width is 5 units. What is the approximate length of the diagonal of the rectangle?

4.9 units
6 units
8.6 units
9 units

Answer 1

we have to apply the theorem of Pitagora, namely:
\[d = \sqrt {{L^2} + {W^2}} = \sqrt {{7^2} + {5^2}} = ...\]
where d is the diagonal

Answer 2
