Question

Points D and E are midpoints of the sides of triangle ABC. The perimeter of the triangle is 48 units.

Triangle A B C is shown. Point D is the midpoint of side A B and point E is the midpoint of side B C. The lengths of A D and D B are 3 t, the lengths of B E and E C are 4 t, and the length of A C is 7 t + 6.

What is the value of t?

2
3
6
8

Answer 1

The value of t is 2.

Step-by-step explanation:

• Given,the perimeter of the triangle is 48 units.
• That means that the sum of  all sides of the triangle is 48 units.

⇒AD+DB+BE+EC+AC=48units.

⇒3t+3t+4t+4t+7t+6=48units.

⇒21t=42units

⇒t=$\dfrac{42}{21}$units

⇒t=2units.

• ∴The value of t is 2.
