(a+3)(a-2)
(a² -2a +3a - 6) =0
(a² + a - 6 ) = 0
Use splitting the middle term
a² + 3a - 2a - 6 = 0
a(a+3) - 2(a+3) = 0
(a-2)(a+3) = 0
Values of a are
a - 2 = 0
a = 2 .....(i)
a+3 = 0
a = -3 .....(ii)
Draw out a number line with the values 0, 5, 10, 15, 20, 25, 30, etc (basically multiples of 5)
Then plot a point at 25
-----------------
Or you can draw out a number line with the multiples of 10, so with the values 0, 10, 20, 30, ...
Then plot a point at the exact midway point between 20 and 30 to represent the value 25
Answer:
Since the area of a triangle is 1/2 base times height, it should be a=1/2(10)(12m)
So the area would be 60 meters squared.
