The perimeter of an isosceles triangle is 25 ft. the length of the third side is 2 ft less than the length of one of the equal sides. find the measurement of the three sides of the triangle.

The side lengths are 9, 9 and 7.

Step-by-step explanation:

The sum of the 2 equal sides plus the shorter side is 25 ft.

Representing these unknowns:

2 sides are of length s, and the third (shortest) side is then s - 2.

Thus,  s + s + (s - 2) = 25, or 3s = 27.  Thus, s = 9 and s-2 = 7

The side lengths are 9, 9 and 7.

16 kids because 2 times 8 equals 16

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.
