Answer:
22m by 9m.
Step-by-step explanation:
1980000 cm^2 = 1980000 / 1000 = 198 m^2.
If the length is L and the width is W, then
2L + 2W = 62
LW = 198
L = 198/ W
Substitute for L in the first equation:
2W + 2(198/W) = 62
Multiply through by W:
2W^2 + 396 = 62W
2W^2 - 62W + 396 = 0
W^2 - 31W + 198 = 0
(w - 22)(W - 9) = 0
so W = 22 or 9.
when W = 22 . L = 198/W = 9
As L is the longest side L = 22 and W = 9m.
