Answer 2

Answer :

›»› The Area of a traingle is 42 cm².

Given :

• Base of a traingle = 12 cm
• Height of a traingle = 7 cm

To Find :

• Area of a traingle = ?

Solution :

As we know that

→ Area of traingle = ½ * b * h

→ Area of traingle = ½ * 12 * 7

→ Area of traingle = 1 * 6 * 7

→ Area of traingle = 6 * 7

→ Area of traingle = 42

║Hence, the Area of a traingle is 42 cm².║
