1)360 (400*.9)
2)342 (380*.9)
3)119 (140*.85)
4)28 (35*.8)
4a-2=a+4
+2 to both sides
4a=a+6
-a from both sides
3a=6

Answer:
1944x^2.
Step-by-step explanation:
sqrt 2x^2 * sqrt18^5
= sqrt2x^2 * (sqrt(9^5*2^5))
= sqrt 2 x^2 * (sqrt9^5 * sqrt 2^5)
= sqrt2 x^2 * (243* sqrt2^5)
= 2^0.5 (243 * 2^2.5) x^2
= 2^3 * 243 x^2
= 1944x^2.
area of perimeter : length × height
= 10.8km × 6km
=64.8km^2
