Question

ABCD is a traingle.AB=10cm, BC=6cm.then ,what is the area of the rectangle? and what is the area of triangleAPB?​

Answer 1

Answer:

In Given Triangle ABC 

AC2+ AB2 = BC2

(6*6)+(8*8)= BC2

BC2=64+36

BC2=100

BC=10

Area of Triangle ABC= 8*6/2

                               =24 Cm2

Semiperemetre of ABC= (8+6+10)/2

                                  =12 cm 

Radius of circle=  Area Of Triangle /Semiperimeter of triangle

                       =  24/12

                        = 2 cm 

Hence Radius of circle is 2 cm 

hope it became easy to understand by the diagram...
