Question

Inside a rectangular garden 21m long and 17m wide, a 1.5m. margin has been left for planting tuberoses,and grass has been planted in rest of area. If 3 tubueroses plants can be planted in 1m² ,how many tuberose plants can be planted in the garden​

Answer 1

Answer:

First take the area of garden=21*17= 357 m^2

then the area covered by margins=17*1.5(along width)=25.5

so total area covered by margins along the width is 51.0

area covered by margins along the length=21*1.5=31.5

total area covered along the length=63.0

minus the area of the squares made due to intersecting of lines=1.5*1.5=2.25

thus area to be subtracted=2.25*4=9

total area covered by margins=(63+51)-9=105 m^2

tuberose to be planted=3*105=315

Answer 2

Answer:

Step-by-step explanation:

First take the area of garden=21*17= 357 m^2

then the area covered by margins=17*1.5(along width)=25.5

so total area covered by margins along the width is 51.0

area covered by margins along the length=21*1.5=31.5

total area covered along the length=63.0

minus the area of the squares made due to intersecting of lines=1.5*1.5=2.25

thus area to be subtracted=2.25*4=9

total area covered by margins=(63+51)-9=105 m^2

tuberose to be planted=3*105=315
