+1982 The perimeters of the two figures shown below are equal. Find the perimeter of the triangle. (Figure not drawn to scale.)
A. 367 units
B. 250 units
C. 2184 units2
D. 30 units
+37146 perimeters are equal
rectangle perimeter = 5x-1 + x + 5x-1 + x
equals triangle perimeter 5x + 6x+7 + 12
5x-1 + x + 5x-1 + x = 5x + 6x+ 7 + 12 solve for 'x' then you can compute the sides of the rect and tri
+37146 Yes, x = 21 , MS......then you use this value of x to compute the sides of the figure to calculate the perimeter of the triangle....
