Question

The area of the triangle below is __ sq units.
A.80
B.21
C.42
D.40

Answer 1

The triangle equation is (side*side)/2

Therefore, we can write the equation as (5*16)/2

After you calculate the equation, we can get the answer of 40, the answer would be D.

Hope that helps :D

Answer 2

Option D is correct

40 square units

Explanation:

Area of the right angle triangle(A) is given by:

`A=(1)/(2)bh` ....[1]

where, b is the base and h is the height of triangle respectively.

As per the statement:

From the given triangle:

b = 16 units and h = 5 units

Substitute in [1] we have;

`A = (1)/(2) \cdot 16 \cdot 5 = 8 \cdot 5 = 40` square units

Therefore, the area of the given triangle is, 40 sq units
