Question

the breadth and perimeter of a rectangular field are 30cm and 1.8m respectively. find the length of the field

Answer 1

Answer:

1.8 m = 1.8×100cm = 180cm

A.T.Q

Perimeter = 180

2(l+b) = 180

2(l+30) = 180

2l + 60 = 180

2l = 180 -60

2l = 120

l = 120/2

l = 60

Therefore length = 60cm
