Question

The perimeter of arectangle plot is 152m and it,s area is 1428m we need to find the lenght and breadth of the rectangular plot represent the problem situation ib the foam of a quadratic equation

Answer 1

Explanation:

Given that,

2(l+b) = 152.............(i)

l×b=1428...............(ii)

from(i) from(ii)

2l+2b= 152 b=1428/l

l+b=76

l+1428/l = 76

l² + 1428 = 76l

l²-76l+1428=0

l²-34l-42l+1428=0

l(l-34) - 42(l-34)=0

l-34=0 or l-42=0

l= 34 or 42

putting l = 42cm putting l = 34cm

b =1428/42 b=1428/34

=34cm =42cm
