**Answer:**

A...similar triangles

**Step-by-step explanation:**

option b... the two triangles are not congruent

option c... the area of ∆AED= 3, ∆ACB= 12.. half of 12 is 6.. wrong

option d. perimeter of ∆AED= 8.60, area of ∆ACB = 12... one fouth of 12 =3. wrong.

option A.. similar triangles have the same shape but they necessarily don't need to have the same size. ... correct! both triangles are right angled triangles.

note.. perimeter is summation of all sides..

solving unknown side use Pythagoras formulae

hyp= √ height (sq) + base (sq)

area of ∆ = 1/2 * base * height...

Where the two Lines intersect and or meet

The bar or line the is placed over repeating digits in a decimal in called a vinculum

**Answer:**

294

**Step-by-step explanation:**

The distributive property for multiplication is as follows :

a(b+c) = ab + ac

We need to evaluate 6 times 49 i.e. 6(49).

We can write 49 as (50-1)

6(50-1) = 6(50+(-1))

Here, a = 6, b = 50 and c = -1

So,

6(50+(-1)) = 6(50) + 6(-1)

= 300-6

= 294

So, answer is 294. Option (A) is somehow correct.
