Question

Find the area and perimeter.

Hint: The height of a non-right triangle is the length of the segment of a line that is perpendicular to the base and that contains the opposite vertex.

24x; 10x + 8
12x; 7x + 3
24x; 5x + 14
12x; 5x + 14

Answer 1

Area =a*h/2
Area = 3x*8/2
Area = 12x

Perimeter =a+b+c
a= 8
b=x+9
c= 4X-3
Perimeter =(8)+(x+9)+(4x-3)
Perimeter =8+x+9+4X-3
Perimeter =5x+14
Answer: 12x; 5x+14
