Question

May I please get help with finding the centimeter and inches?

Answer 1

In a scale model of television, 1cm = 10 inches

`1cm\colon10\text{inches}`

(a) The length of real TV = 80 inches, then the length of the TV in scale model:

`\begin{gathered} 1cm\colon10\text{inches} \\ x\colon80\text{inches} \\ x=(80)/(10)cm \\ x=8cm \end{gathered}`

Hence the length of the TV in scale model = 8cm

(b) In the scale model, the height of the TV =5cm, the height of the real TV will be:

`\begin{gathered} 1cm\colon10\text{inches} \\ 5cm\colon x \\ x=5(10)in\text{ches} \\ x=50\text{inches} \end{gathered}`

Hence the height of the real TV = 50inches
