Question

A school has rectangular playground, whose breadth
is two-third of its length. Adjacent to this ground,
a right isosceles triangle shaped piece of land is there, which is to be developed as a rose garden. A nearby hardware whole sale shop comes forward to donate 200m of wire.

find the number of rose saplings to be purchased for the garden, if each sapling requires 2m square of land.​

Answer 1

Step-by-step explanation:

ar. of rose garden = ½b²= ½×2x/3×2x/3 = 2x/18 = X/9

x/9= 200m => X=1800m

Now,

No. of saplings = 1800/2 = 900 saplings

Answer 2

step by step explanation : Area of rose garden = 1/2×l ×b=1/2×2x/5×2x/5=2xsquare/5

then 2xsquare/25=200

2xsquare=200/25

2xsquare=5000

x2=2500

x=root of 2500

x=50

no of saplings=50x3=150 saplings
