By using Pythagorean Theorem,
C^2= (10)^2+ (9)^2
C^2=100 + 81
C^2=181
C= 13.4cm
Hope it helps!
Answer: 120 km^2
Explanation:
S = (9x3) + (9x4) + (4x3)2/2 + (9x5)

Answer: The correct option is option third .
Explanation:
The given equation are,

In the second equation the like terms are aligned, therefore, we have to aligened only first equation.
The first equation is,

Subtract 0.8 from both the sides.


Add 0.4y on both the sides.


So, after aligned the system of equation have two equations.


Both equation are show in third option, So third option is correct.
