The perimeter of triangle IJH is determined as 21 units.
How to calculate the perimeter of triangle IJH?
The perimeter of triangle IJH is calculated by applying the following formula as shown below.
If IJ is the mid segment of triangle FGH, then
IH = IF = ¹/₂FH
IH = ¹/₂ x 11
IH = 5.5
Also, HJ = JG = ¹/₂ x GH
HJ = ¹/₂ x 15
HJ = 7.5
The perimeter of triangle IJH is calculated as follows;
Perimeter = IH + IJ + HJ
Perimeter = 5.5 + 8 + 7.5
Perimeter = 21 units
Thus, the perimeter of triangle IJH is determined as 21 units.
