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

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

here b = 14 and h = 4, hence

A = \frac{1}{2} (14 × 4) = 28

Find the midpoint of the segment with the given endpoints. ​ (9​,9​) and ​(6​,8​)
mars1129 [50]

<u>Answer:</u>

The mid-point is (7.5, 8.5).

<u>Step-by-step explanation:</u>

We are given two points (9​,9​) and ​(6​,8​) as the endpoints for a line segment and we are to find the midpoint of this segment.

We know that the formula for finding the mid point is:

<em>Mid point = (\frac {x_1 + x_1 }{ 2 } ,\frac { y_1 + y_2} {2} )</em>

So substituting the given values of the coordinates of the endpoints in the above formula to get:

= (\frac {9 + 6}{2} , \frac {9 + 8}{2} )

= (\frac {15}{2} , \frac {17} {2} )

=(7.5, 8.5)

Therefore, the mid-point is (7.5, 8.5).
