1200cm
20x50= 1000x1/2x2= 1000
10x20=200x2x1/2=200
1000+200=1200
the area of the kite is 1200 cm
We are given a system of equations,

This will translate into a 2x2 matrix of coefficients (because 2 equations and 2 unknowns),

The matrix will then be applied to the vector (lower dimensions on top),

And the result vector will be whats on the other side of equals sign,

So to put everything together,

Hope this helps :)
Answer:
y = 48, x = 11
Step-by-step explanation:
6x = 3x + 33
3x = 33
x = 11
6x + 3x + 33 + y = 180
66 + 33 + 33 + y = 180
66 + 66 + y = 180
132 + y = 180
y = 180 - 132
y = 48
