Answer:

sides 1 and 2 are 150 m. Side 3 is 270m

Step-by-step explanation:

perimeter = 570 m

sides 1 and 2 = x

side 3 = 2x-30

permeter = side+side+side

570=x+x+2x-30

600=4x

x = 150

The layout of a playground uses the scale 1:50. If the dimensions of the playground in the layout are given by 180 cm x 240 cm,

Ainat [17]

The area of the playground of dimensions 18 and 240is 432 $m^{2}$ .

Given If the dimensions of the playground in the layout are given by 180 cm x 240 cm.

The area of rectangle is length *breadth.

The given playground is in the shape of rectangle because there are two sides given and both the sides are different. In a rectangle length of opposite side found to be equal and each side form an angle of 90 degree.

Area=length*breadth

=180*240

=43200 $cm^{2}$

We have to convert in meters so we have to divide by 100.

Area=43200 $cm^{2}$

=43200/100

=432 $m^{2}$

Hence the area of playground having dimensions 180 cm and 240 cm is 432 $m^{2}$ .
