Question

What is the area of this triangle? Please help me.

Answer 1

8 units²

Explanation:

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

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

here b = LK = 7 - 3 = 4 units

and h = J → x- axis = 4 - 0 = 4, hence

A =
`(1)/(2)` × 4 × 4 = 8 units²
