Answer 2

Answer:

l = 30m,  b = 50m    (or)  l = 50m,  b = 30m

Step-by-step explanation:

perimeter  =  160

2(l+b)     160

l+b   =80

l   =  80 - b  .......(1)

 Area  = 1500

l x b  = 1500

(80 - b ) x b  = 1500

80b  - b² - 1500  = 0

b² - 80b + 1500  = 0

(b - 50 ) ( b - 30 )  = 0

b = 50  , b = 30

when b = 50  ,  l = 80 - 50

                           = 30m

when b = 30  ,then  l = 80 - 30

                                   = 50m
