Answer:
Upper left coordinate (-8,8),
upper-right coordinates (-3,8)
Lower left (- 8, 5)
Lower right = ( - 3, 5)
Step-by-step explanation:
Given that :
Upper left coordinate (-8,8),
upper-right coordinates (-3,8).
x1, y1 = (-8, 8) ; x2, y2 = (-3, 8)
The distance, d = √(x2-x1)² + (y2 - y1)²
d = √(-3 + 8)² + (8 - 8)²
d = √25
d = 5
Recall :
Area = length * width
Length = distance, d
15 = 5 * w
15 = 5w
w = 15 / 5
w = 3.
Hence, coordinate becomes ;
x3, y3 becomes (- 8, (8-3)) = (-8, 5)
x4, y4 becomes (-3, (8-3)) = (- 3, 5)
Hence, we have
Upper left coordinate (-8,8),
upper-right coordinates (-3,8)
Lower left (- 8, 5)
Lower right = ( - 3, 5)
