the portion of a triangle is mostly a million/2 the backside situations the top! no be counted if it is isosceles, the two "different" facets ought to be equivalent. you are able to not have 3 diverse lengths on an iso. So the "height" ought to be one hundred tiers, and the two facets 40. the top is the perpendicular to the backside. flow from there.

Distance between U & V = sqrt((v2-u2)^2 + (v1-u1)^2) = sqrt((2-2)^2 + (-8-1)^2) = sqrt((0^2+(-9)^2) = sqrt(0+81) = sqrt(81) = 9
Distance between U & W = sqrt((w2-u2)^2+(w1-u1)^2) = sqrt((6-2)^2+(-4-1)^2) = sqrt(4^2+(-5)^2) = sqrt(16+25) = sqrt(41)
Distance between V & W = sqrt((w2-v2)^2+(w1-v1)^2) = sqrt((6-2)^2 + (-4-(-8))^2) = sqrt((4^2 + 4^2) = sqrt(32) = sqrt(2)sqrt(16)=4sqrt(2)
Perimeter = 9 +sqrt(41) + 4sqrt(2) = 21.0599785

use the distance formula
forfindindthe sides
UV=rt(81)=9
VW=rt(32)=4rt2
UW=rt(41)
therefore perimeter
=9+4(1.414)+6.43
=21.09 sq.units

18 units i think
or .........
(X2-X1) + (Y2-Y1)
M=---------------------------
2
i think that is the distance formula! is it?
