Question

Find the area of triangle which sides are120m,22m and 120m​

Answer 1

Answer:

1320 metre square

Step-by-step explanation:

Area of triangle. A= 1/2 b.h consider base as 22m and height as 120m. ie 1320 metre square.

Answer 2

Given :

Sides of triangle 120 m,22m and 120m

To Find :

Area of the triangle

$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

First of know which type of triangle is formed here :

From above we we see that the two sides say 120m and 120m are equal which means two sides of a traingle are equal so it's a isosceles triangle.

Isosceles triangle: A triangle whose any two sides are equal are called isosceles triangle.

see image attach above ^^

Come to the question:

$\bold{\boxed{Area \: of \: Isosceles \: Triangle = \frac{1}{2} \times base \times height}}$

=>Base is 22m according to the property of Isosceles Triangle given below.

$Area \: of \: Triangle = \frac{1}{2} \times 22\times 120$

$= > 60 \times 22 = 1320 {m}^{2}$

Thus,Area of Triangle is $\bold{\red{1320 {m}^{2}}}$

Some properties of Isosceles Triangle

• 2 sides and along with 2 angles are equal.
• The other or third sides of an Isosceles which is not equal is called the base of the triangle.
• The unequal angle of the third side is called "apex angle".
