Question

M is a point on AB so that the ratio of AM to MB is 3:4.If the length of MB is 14cm,find the length of :
(a)AM
(b)AB​

Answer 1

Answer:

M is mid point of AB.

Therefore AM=MB and CM is median.

△BMC=21△ABC=21×24=12

Areaof△CDM=Areaof△DME

Areaof△BED=△BMD+△MDE

Areaof△BED=△BMD+△CDM

Areaof△BED=Areaof△BMC

                               =12Sq.unit
