Question

Te length of a rectangular field is 5 times its Breadth. if its area is 180 sq cm , find the sides of te field
​

Answer 1

Answer:

given-

length=5(breadth)

area=180sq cm

let area=a, length=l, breadth=b

Now,

l=5(b)

a=l*b

a=5(b) *b

a=5 b^2

180=5b^2

b^2=36

b=√36

b=6 ans

l=5(b)

l=30 ans.
