Answer:
11 by 18
Step-by-step explanation:
Length = L
Width = W
LW = 198 -------------- [ Equation 1 ]
2( L + W) = 58 -------------- [ Equation 2 ]
Equation 2:
2( L + W) = 58
L + W = 29
L = 29 - W
Substitute L = 29 - W into Equation [ 1 ].
W(29 - W) = 198
29W - W² = 198
W² - 29W + 198 = 0
(w - 11) (w - 18) = 0
W = 11 or W = 18
W = 11
L = 18
