Question

BE, CD are two medians in ABC intersect at point M , the perimeter of MDE = 12 cm. Find: The perimeter of MBC ​

Answer 1

24 cm.

Explanation:

drawing a picture, you will see that DE is parallel to BC (DE//BC) and triangle DME is simillar to triangle CMB by using simillarity triangle of triangle ADE and triangle ABC make you know the length of BC is 2 times of DE, using simillarity triangle again with triangle DME and triangle CMB.

Therefore, the perimeter of MBC is 2*12 = 24 centimeters.
