If onetree can be planted in an area of 10 sq m.who can plant more trees in his field? How manymore trees can he plant?
Answer» Answer: For RAHUL's field, GIVEN, l=400m b=200m Therefore, perimeter=2(l+b) =2(400+200)m =1200m Therefore, COST for FENCING the field=Rs1501200 =Rs 180000 Again, Area of the field=lb =400200 m² =80000 m² Therefore,the no. of trees Rahul can plant=80000m²/10m² =8000 For Ramu's Field, Given, side=300m Therefore, Perimeter=4s =4300m =1200m Therefore, cost of fencing the field=Rs1501200 =Rs 180000 Again, Area of the field=SS =300300 m² =90000m² Therefore, no. of trees ramu can plant=90000m²/10m² =9000 Therefore, Ramu can plant more trees than Rahul by 9000-8000=1000 trees

Rahul_ owns a rectangular field of length 400 m and breadth 200 m. His friend Ramu_ owns asquare field of length 300 m. Find the cost of fencing the two fields at 150 per meter. If onetree can be planted in an area of 10 sq m.who can plant more trees in his field? How manymore trees can he plant?

Answer»

Answer:

For RAHUL's field,

GIVEN,

l=400m

b=200m

Therefore, perimeter=2(l+b)

=2(400+200)m

=1200m

Therefore, COST for FENCING the field=Rs150*1200

=Rs 180000

Again,

Area of the field=l*b

=400*200 m²

=80000 m²

Therefore,the no. of trees Rahul can plant=80000m²/10m²

=8000

For Ramu's Field,

Given,

side=300m

Therefore, Perimeter=4*s

=4*300m

=1200m

Therefore, cost of fencing the field=Rs150*1200

=Rs 180000

Again,

Area of the field=S*S

=300*300 m²

=90000m²

Therefore, no. of trees ramu can plant=90000m²/10m²

=9000

Therefore, Ramu can plant more trees than Rahul by 9000-8000=1000 trees

A caterpillar is climbing a tree of height 10 metersand he climbs 2 meter in 1 day and take rest for 1 dayin which he slides down 1 meter how many days willit take for the caterpillar to do a round trip i.e bottomto top and top to bottom.Ans

Answer»

Step-by-step explanation:

On One DAY - - 2m

On One Day It RESTS - 2-1

∴ In 2 Day It will climb 1m Just Like That

On 3 day it will climb=3m

On 4 day it will climb = 3-1=2m

On 5 day it will climb = 4m

On 6 day it will climb = 4-1=3m

On 7 day it will climb = 5m

On 8 day it will climb = 5-1=4m

On 9 day it will climb = 6m

On 10 day it will climb = 6-1=5m

On 11 day it will climb = 7m

On 12 day it will climb = 7-1=6m

On 14 day it will climb = 8m

On 15 day it will climb = 8-1=7m

On 16 day it will climb = 9m

On 17 day it will climb = 9-1=8m

On 18 day it will climb = 10m

IT will Take 18 days
