Question

What is the area of this triangle in coordinate plane

A) 5 units^2
B) 6 units^2
C) 7 units^2
D) 12 units^2

Answer 1

B

Explanation:

The area (A) of a triangle is found using the formula

A =
`(1)/(2)` bh ( b is the base and h the perpendicular height )

here b = 4 and h = 3, hence

A =
`(1)/(2)` × 4 × 3 = 6 units ² → B

Answer 2

base = 4

height = 3

area = base*height/2

area = 4*3/2

area = 12/2

area = 6, so the answer is choice B
