Question

The triangle below has an area of 10 units squared.

Answer 1

The value of x (which is also the height of this triangle) is x = 5 units.

Explanation:

The formula for the area of a triangle of base b and height h is

A = (1/2)(b)(h).

Here A = 10 units² = (1/2)(4 units)(x).

Multiplying both sides by 2 yields 20 units² = (4units)(x), and thus 20 units²

Answer 2

x = 5 units

Explanation:

area = 1/2bh

10 = 1/2(x)4)

2x = 10

x = 5
