Answer 2

Here us your answer bro!

d) none.

PLEASE MARK IT THE BRAINLIEST.

Step-by-step explanation:

Area of a triangle= ½× base×height.

Let's consider 20 cm be the base.

so the 10 cm is the other side.

therefore,

½×20×height = 80

= 10×height = 80

= height= 80/10= 8

so height is 8cm.

Now we have a right angle triangle ABD.

So by Pythagoras property we have

hypotenuse the longest side.

so,

h²=b²+p² [ h is hypotenuse b is vase and p is

perpendicular or height.]

h= √20²+8²

= √464

So √464 cm is the answer.

But in the options we don't have the above answer so the answer will be NONE.
