Answer:
Below.
Step-by-step explanation:
We apply the quotient rule:
dy/dx = ( tanx * 3x^2 - x^3 * sec^2x) / (tan^2 x)
= x^2( 3tanx - xsec^2x) / tan^2x

The area of the playground of dimensions 18 and 240is 432
.
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 
We have to convert in meters so we have to divide by 100.
Area=43200 
=43200/100
=432 
Hence the area of playground having dimensions 180 cm and 240 cm is 432
.
