What is the length of the dotted line in the diagram below? round to the nearest tenth

Question 1

Question 2

Answer:

8.1

Explanation:

$From \: the \: diagram, \: we \: can \: see \: a \: rectangle \: joined \: to \: a \: right \: angled \: triangle\: and \: the \: hypotenuse \: appears \: to \: be \: the \: breath \: of \: the \: rectangle$

$So \: using \: Pythagoras \: theorem \: to \: find \: the \: hypotenuse \: of \: the \: triangle.$

$\sqrt{4 {}^(2) + 5 {}^(2) } = √(41)$

= 6.4

$To \: find \: the \: dotted \: line, \: inside \: the \: rectangle \: we \: also \: use \: Pythagoras \: Theorem \: because \: of \: the \: right \: angled \: triangle \: formed$

$\sqrt{ {6.4}^(2) + 5 {}^(2) }$

√(65.96) = 8.1215

$≈8.1 \: to \: the \: nearest \: tenth$
