Hey there!
(3x)^2 - 2x^2
= (3(-2))^2 - 2(-2)^2
= -6^2 - 2(4)
= 36 - 8

Answer: Area = 389.5cm^2
Explanation:
Area = 104.5cm^2
Width = 9.5cm
Find Length:
L = A/W
L = 104.5/9.5
L = 11cm
Find the enlargement:
let x be the enlargement:
9.5cm + x = 19cm
x = 19 - 9.5
x = 9.5cm
Thus, the enlargement is 9.5cm.
L (after enlarging) = 11 + 9.5 = 20.5cm
W (after enlarging) = 19cm
Find area after enlarging:
A = 20.5 x 19
A = 389.5cm^2
