You find the perimeter of a geometric figure by adding the measure of its sides. If the perimeter of the figure below is 100 cm, write and solve an equation to find the value of x. 3x
6x - 2
2x + 4
3x

x=6

Step-by-step explanation: combine x =14x, 4-2 =2 so +2 to both sides gives u 98 and divide by 14.

2(3x) + 2x +4 + 6x -2 = 100

X=6

i dont understand the question? ?

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
