Question

In the given figure,angle abc=90 degree and P is the mid point of AC.Find the length of AB.please answer this question...

Answer 1

AB is already marked 3 cm in the figure....!!??

Answer 2

Answer:

The length of AP is 2.5 cm.

Step-by-step explanation:

Given,

m∠ABC = 90°,

AB = 3 cm and BC = 4 cm,

To find : The length of AP.

By Pythagoras theorem,

$AC^2=AB^2+BC^2$

$=4^2+3^2$

$=16+9$

$=25$

$\implies AC = 5$ ( We did not consider negative value because, the length can not negative ),

Also, it is given that,

P is the mid point of AC,

$\implies AP =\frac{AC}{2}=\frac{5}{2}=2.5\text{ cm}$
