Question

i this triangle ab =3.5 ,bc=3.5
find area of the triangle..​

Answer 1

Answer:

are of triangle = 1/2 * base * height

= 1/2 * 3.5 * 3.5

= 6.125

u have not mentioned any unit of the side..

so I have not written..

Answer 2

Step-by-step explanation:

ANSWER:-

• The given Triangle is a Right angle Triangle
• We determine the right angle triangle by seeing the angle.
• Any one angle must be equal to 90°

Now, we know that to find out the area of a right angle Triangle :-

$\dfrac{1}{2} \times b \times h$

• Where b is base
• Where h is height.

Now in this triangle,

• Base is AB
• Height is BC
• Both the values are 3.5

So, placing the values,

$\dfrac{1}{2} \times 3.5 \times 3.5$

$\dfrac{1}{ \cancel{2}} \times \cancel{12.25} = 6.125$

So, the answer is

$6.125 \: {u}^{2}$

is the required Area.

Note:-

• This area formula is applicable only and only for right angle triangles which is found if any one angle is equal to 90°.
• u² is unit square as any unit is not mentioned.
