Answer:
1.25 and - 1.25
Step-by-step explanation:
additive inverses: a number and its opposite have a sum of 0
x and y are opposite number, one positive and another negative
distance = 2.5 with midpoint "0"
x = 2.5/2 = 1.25
y = -1.25
The answer is 2240m².
Given that the formula of area of trapezium is A = 1/2×(a+b)×h where a and b represents the length and h is height :
622.27
- $87.45 + (- $24.76) + (-17.29) = $-129.5
$143.87 + $348.90 = $492.77
492.77 - (-129.5) = 622.27
