The area of square abcd is 81 square units and the area of triangle ebf is 53 square units. if eb is perpendicular to bf and ae=5, find the length of cf

.

Step-by-step explanation:

The area of the square is=81 square units

⇒

⇒

From figure, AB= 9cm, and it is given that AE=5cm, therefore EB=4cm.

Now, Area of triangle EBF=

53=

As, BF=BC+CF

And BC is the sie of square which is equal to 9cm

Therefore,

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

i think is g(1)=-1.

hope that i can
