Question

A bed of roses is as shown in the adjoining diagram. In the centre, is a square and on each side is a semi-circle. The side of the square is 21 m. If each rose plant needs 6 m² of space, find the number of plants.

Answer 1

Answer: 189

Step-by-step explanation:

The question is incorrect as the side of square is in cm but area that each plant takes is in m^2 so by the question we wont be able to grow a single plant ( as the area where plants has to grow is less than the area of one plant itself)

So i am providing solution assuming both the units are same i.e. in meters

Calculate the sum of areas of Square and 4 semicircles on its side

Area of Square = 21x21 = 441 m^2

Area of 4 semi circles = 4x 1/2 x 22/7 x 21/2 x 21/2 = 693 m^2 ( The radius of each semicircle will be Side of the square divided by 2)

Sum of the areas = 441+ 693 = 1134m^2

Now to get the number of rose plants divide the area taken by each rose plant i.e. 6m^2 to the total area i.e 1134m^2

So 1134/6 = 189 rose plants
