Answer: 17.5

Step-by-step explanation:

x = -5

f(-5) = -x^2+0.5x-5

= -(-5)^2 + 0.5(-5)-5

= 5^2 + (-2.5) - 5

= 25 - 2.5 - 5

= 17.5

Area for a triangle is (1/2) bh or bh/2
So using this info, b = 1.5 m and h = x and A = 1.5 m^2

A = bh/2
1.5 = 1.5x/2
Multiply both sides by 2 to get rid of fraction ... 3 = 1.5x
Divide both sides by 1.5 ... 2 = x so x= 1.5 m
