area of rahul's field = 400*200 = 80000m²

area of ramu's field = 300*300 = 90000m²

cost of fencing the fields = 150*(80000+90000) = ₹25500000

no. of trees rahul can plant = 80000/10 = 8000

nom of trees ramu can plant = 90000/10 = 9000

hence, ramu can plant 1000 more trees. (9000-8000=1000)

Answer 2

$\huge\mathbb{SOLUTION:-}$

$\bold{Given:-}\begin{cases}\sf{Dimensions\:of\:\: Rahul\: field=400m\:and\:200m}\\ \sf{Dimensions\:of\: His \: friend\: Field=300cm}\end{cases}$

• 1st find the area of rahul Field

$\boxed{\sf{Area\:of\: rectangle=Length\times breadth}}$

$\bf\underline{\underline{\red{According\:to\: Question:-}}}$

$\sf\mapsto Area\:of\:\: rahul Field=400m\times 200m\\ \\ \sf\mapsto Area\:of\: rahul\:field=80000m{}^{2}$

• The area of rahul field is 80000 square metre

• Now the area of his friend field which is in shape of square

$\boxed{\sf{Area\:of\: square=side{}^{2}}}$

$\sf\mapsto Area\:of\: his\: friend\:field=(300m){}^{2}\\ \\ \sf\leadsto Area\:of\: his\: Friend\:field=90000m{}^{2}$

• now The total area of both fields

$\boxed{\sf{\purple{Total\:area\:of\:both\: field=Area\:of\: rahul\: field+Area\:of\: his\: friend\: field}}}$

$\sf\implies Total\:Area=80000m{}^{2}+90000m{}^{2}\\ \\ \sf\implies Total\:Area=170000m{}^{2}$

• Now the cost of fencing the field is 1.50 Rs per square metre

$\sf\leadsto cost\:of\: fencing=1.50\times 170000m{}^{2}\\ \\ \sf\leadsto Cost\:of\: fencing=255,000Rs$

$\boxed{\sf{Cost\:of\: fencing\:both\: field=255,000rs.}}$

• If one tree is planted in a area of 10 square metre

$\sf\implies No.\: trees\: Rahul\:planted=\cancel{\frac{80000}{10}}\\ \\ \sf\implies No.\:Trees\:Rahul\: planted=8000$

• Rahul planted 8000 trees

• Now his friend

$\sf\implies No.\: trees\: Rahul's\:friend\:planted=\cancel{\frac{90000}{10}}\\ \\ \sf\implies No.\:Trees\:rahul's\: freind \:planted=9000$

$\sf\leadsto More\:trees\: His\: friend\: planted=9000-8000\\ \\ \sf\implies 1000$

• Rahul's friend planted more trees

$\boxed{\sf{\purple{His\: friend\: planted\:1000\:More\:Tress\:}}}$
