the diagram shows a scale drawing of a playground. The scale of the drawing is 1:500. Work out the perimeter. Give answer in met
IceJOKER [234]

Answer:

The perimeter of the playground is 65 metres

Step-by-step explanation:

Questions like this requires attachment; See attachment for diagram.

From the diagram, we have the following parameters

Length = 2cm

Width = 4.5cm

Required

Calculate the parameter of the actual diagram

First, the actual length and width has to be calculated;

Given that the scale drawing is 1:500

Actual\ Length = 500 * 2cm = 1000cm

Actual\ Width = 500 * 4.5cm = 2250cm

Now, the perimeter can be calculated;

Perimeter\ of\ a\ Rectangle = 2(Length + Width)

Perimeter = 2(1000cm + 2250cm)

Perimeter = 2(3250cm)

Perimeter = 6500cm

However, the question requires answer to be in meters

If 100 cm = 1 m, then

6500cm = \frac{6500m}{100}

6500cm = 65m

Hence, the perimeter of the playground is 65 metres

HELP RN, QUESTION OVER 40 POINTS.
elena-14-01-66 [18.8K]
ANSWER:

A diagonal fold which runs from the bottom-left corner to the top-right corner.

This would be the angle bisector of XAB as it would run directly through the centre of the angle, thus bisecting it.

I have attached an image which visually represents this. The blue lines are meant to be the angle XAB while the red line is the diagonal fold / angle bisector.

Hope this helps! <3
