Question

A fence borders a triangular shaped field. A scale drawing of the fence is shown. The scale of the drawing to the actual size of the field is 30 mm :5m

Answer 1

The actual measurements of the Fence are;

$13.33\text{ m , 30.67 m and 7.33 m}$

Here, we want to calculate the measure of the sides of the fence in meters

Basically, we will be converting from the scale on drawing to the real measurements

We have this as follows;

Mathematically;

a) 30 mm to 5 m is the scale

80 mm to x m

Thus;

$x\text{ = }\frac{80\times5}{30}\text{ = 13.33 m}$

b) 30 mm to 5 m

184 mm to x m

$\begin{gathered} x\text{ = }\frac{184\times5}{30} \\ x\text{ = 30.67 mm} \end{gathered}$

c) 30 mm to 5 m

44 mm to x m

$\begin{gathered} x\text{ = }\frac{44\times5}{30} \\ x\text{ =7.33 mm} \end{gathered}$
