What is the area of the triangle with a base of 6 mm and a height of 9
mm?*

A=27 mm²

Step-by-step explanation:

To find the area of a triangle, the formula is . Since we know the base and height, we can directly plug them into the formula.

                 [divide]

                      [multiply]

The area of the triangle is A=27 mm².

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
