We know that the points at which the parabola intersects the x axis are
(-5,0) and (1,0)
So the extent between these two points would be the base of the triangle
lets find the length of the base using the distance formula
![\sqrt{[(-5-1)^{2}+(0-0)^{2} ]}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%5B%28-5-1%29%5E%7B2%7D%2B%280-0%29%5E%7B2%7D%20%5D%7D%20%20)
the base b=6
We will get the height of the triangle when we put x=0 in the equation
y=a(0+5)(0-1)
y=-5a
so height = -5a (we take +5a since it is the height)
We know that the area of the triangle =
× 6 × (5a) = 12
15a=12
a=

This is the associative property for addition. In informal language, it says under addition, the order of the addition is not critical.
you need another equation to solve them simultaneously since they are two unknown
Answer:
5.7 feet
Step-by-step explanation:
Total cloth area recquired to make a bag and a towel is 22.23 square feet
Given the area of the cloth recquired to make the bag is 5.13 square feet.
The area of cloth recquired to make the towel is = 22.23-5.13=17.1 square feet
given the height of the towel = 3 feet
let the length of the towel be x
We know that 
area=3x
therefore the length of the towel is 5.7 feet
