Area of triangle is 1/2 times base times height
lets say the base is from x1,y2 to x1,y1 the distance is 6 units
1/2 times 6 times height
from x1,y1 to x3,y3 is 7 units to the right
1/2 times 6 times 7=3 itmes 7=21
area=21 square units or
21 units^2
Solution :
Now, simplifying the given equation :
( Using, (a+b)² = a² + 2ab + b² )
Therefore, the simplification of given equation is :
the x and y intercept would be
x= (-4,0) y=(0,-3)
Given scale:
2 cm = 192 cm on actual wing
The length of wing on the drawing= 8.125 cm
So actual length of wing = 192/2 x 8.125
Actual length of wing= 780 cm
Answer: 780 cm
