Question

the perimeter and area of a rectangular filed are 100 mts and 600sq meters respectively.Find the length and breadth of the filed​

Answer 1

l x b =600

l=600÷b. ....1equation

2(l+b)=100

main l ke value but kr le aa jayega

Answer 2

Step-by-step explanation:

GIVEN:

AREA=600m²

PERIMETER=100m

NOW,

l x b=600......1)

2 x [l+b]=100⇒ l+b=50......2)

⇒ l=600/b.....3)

Putting the value of eq. 3) in eq. 2)

600/b + b=50

⇒600+b²/b=50

⇒600+b²=50b

solving the quadratic eq. gives

b=60m

putting the value of b=60 in eq.3

l=600/b

l=600/60

l=10m

⇒The length of the field is 10m and breadth is 60m.
