Question

Find the measure of PR given rectangle pqrs round answer to the nearest whole number

Answer 1

We can draw the following picture:

where we can see that triangle PSR is a right one. Then, we can apply Pytagorean theorem to find PR:

`(2.6)^2+4^2=PR^2`

then, PR is given by

`PR=\sqrt[]{(2.6)^2+4^2}`

which gives

`\begin{gathered} PR=\sqrt[]{6.76+16} \\ PR=\sqrt[]{22.76} \end{gathered}`

therefore, PR is equal to 4.77 m. By rounding up to the nearest whole number, the answer is PR= 5 m.
