8. A triangle has sides with lengths of 6, 8, and 10 units, and a square has a
perimeter of 28 units. What is the positive difference, in square units,
between the area of the triangle and the area of the square?
a. 1
b. 4
c. 25
d. 100
e. 148

Difference between the area of the triangle and square is 25

Step-by-step explanation:

Area of the triangle = where s =

⇒ s = (6 + 8 + 10)/2 = 24/2 = 12

=

                                    = = = 24 sq. units

Perimeter of the square = 4 × side = 28

⇒ Side of the square = 28/4 = 7 units

⇒ Area of the square = (side)² = 7² = 49 sq. units

Difference = 49 - 24 = 25

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
