Question

Robert needs to attach a diagonal brace to arectangular frame in order to make itstructurally sound. If the framework is 3 feetby 6 feet, find how long the brace needs to beto the nearest tenth of a foot.

Answer 1

Given,

The dimension of the rectangular frame is 3 feet by 6 feet.

Required

The length of the diagonal brass.

The length of the diagonal is calculated as,

`\begin{gathered} Diagonal=√((length)^2+(base)^2) \\ =√((3)^2+(6)^2) \\ =√(9+36) \\ =√(45) \\ =6.7\text{ feet} \end{gathered}`

Hence, the length of the diagonal is 6.7 feet.
