What is the area of a triangle that has a base of 3 feet and a height of 6 feet? a: 18 ft^2 b: 18 ft c: 9 ft^ 2 d: 4.5 ft^2

The formula of area of triangle is given by

Where b is the base and h is the height .

In the given question, base ,b = 3 feet

Height, h= 6 feet

Substituting the values of b and h in the formula, we will get

Correct option is C .

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
