Formulas needed:
Square area = b^2
Rectangle area = bh
Triangle area = bh/2
Parallelogram = bh
Trapezoid area = a+b/2(h)
Rhombus area = pq/2
Even better; use online calculators.
To use these formulas, you need to substitute the values given for b,h,a,b,p or/and q and then solve to get area.
So for this example, since it's a rectangle, you use formula A = bh. Base is 5.1, and height is 6.
Substitute now.
A = bh
= (5.1)(6) (substitute)
= 30.6 (multiply)
Therefore the area is 30.6 m^2. Don't forget the unit measurements, which is *measurement*^2.

Step-by-step explanation:
2A
x=1 y=3
x=4 y=0
y=mx+b
3=m+b
0=4m+b
3=-3m
m= -1
0=-4+b
b=4
y= -x +4
2B
x=2 y=0
x=0 y= -4
0=2m+b
-4=b
b=-4
0=2m-4
2m=4
m=2
y=2x-4
Answer:
It A
Step-by-step explanation:
6 times -2 is -12
6 + -2 is 4
And x +x is x^2
