Answer 1

ANSWER :

›»› The area of the triangle is 120 m².

GIVEN :

• Altitude of a triangle = 20 m.
• Base of a triangle = 12 m.

TO FIND :

• Area of a triangle = ?

SOLUTION :

We have given the values of altitude and base of a triangle are 20 m and 12 m respectively$.$

We know that, altitude and height are same.

• Altitude = Height.

To find the area of a triangle, we use the formula:-

❰ Area of triangle = 1/2 × base × height ❱

• Base = 12 m.
• Height = 30 m.

According to the given question,

On putting values in thr formula, we get::

⇒ Area of triangle = 1/2 × 12 × 20

⇒ Area of triangle = 1 × 6 × 20

⇒ Area of triangle = 6 × 20

⇒ Area of triangle = 120

Hence, the area of the triangle is 120 m².

Answer 2

Answer:

$\huge \bf \: Given$

• Altitude = 20 m
• Base = 12 m

$\huge \bf \: To \: find$

Area of triangle

$\huge \bf \: Solution$

As we know that

Altitude = Height

$\huge \tt \: area \: = \frac{1}{2} \times h \times b$

Here,

H = Height

B = Base

$\sf \: area = \dfrac{1}{2} \times 20 \times 12$

$\sf \: area \: = 1 \times 10 \times 12$

$\huge \bf \: Area \: = 120 \: cm$
