Answer 1

Answer:

( 344 , 205  )

Step-by-step explanation:

original area A = LB

( L -5  )  (  B + 3   ) = LB - 8 = LB + 3L - 5B -15

( L -3  )  (  B + 2   ) = LB +67 = LB + 2L - 3B - 6

3L - 5B = 7

2L - 3B = 73

9L - 15B = 21

10L - 15B = 365

L = 344 ,

3B = 2L -73 = 688 -73 = 615

B = 205

(L , B  ) =  ( 344 , 205  )
