Question

9. In Fig. 12.33, the area of the triangle ABC = 7.2 cm",
CM = MB, and AL = 2 LB. Find the area of the
triangle ALM.
(SC)​

Answer 1

Answer:

The area of triangle ALM is

$1.8cm {}^{2}$

...

Step-by-step explanation:

As AM is the median of the triangle ABC, it divides the triangle into 2 triangles of equal areas...

Therefore, area of triangle ABM=

$7.2 \div 2 = 3.6cm {}^{2}$

In triangle ABM,LM is the median and thus divides the triangle in 2 equal parts...

Therefore,area of triangle ALM=

$3.6 \div 2 = 1.8cm { }^{2}$

Answer 2

Answer is 1.8cm^2

As Am is median of triangle ABC ,it divides triangle in 2 triangles of equal areas .

Therefore, area of triangle ABM = 7.2/2 => 3.6cm^2

In triangle ABM,LM is median and thus divide the triangle in 2 equal parts .

Therefore , Area of triangle ALM => 3.6/2 = 1.8 cm ^2
