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

if the area of a rectangle is represented by 25x^3y^6 and its width is represented by 10xy, express the length of the rectangle

iren [92.7K]

The length of the rectangle in terms of x and y, given that its area is represented by 25x³y⁶ and its width is represented by 10xy is <u>2.5x²y⁵</u>.

The area of a figure is the total space enclosed in two dimensions within its boundary.

The area of a rectangle is given as, area = length*width.

In the question, we are given that the area of a rectangle is represented by 25x³y⁶ and its width is represented by 10xy, and are asked to express the length of this rectangle in terms of x and y.

We know that the area of a rectangle is given as, area = length*width.

Substituting the known values in the equation, we get:

25x³y⁶ = length*10xy.

Rearranging this equation, we get:

length = 25x³y⁶/10xy = (5x²y⁵)/2 = 2.5x²y⁵.

Thus, the length of the rectangle in terms of x and y, given that its area is represented by 25x³y⁶ and its width is represented by 10xy is <u>2.5x²y⁵</u>.
