Area=21

Answer 2

Answer:

• Perimeter of triangle = 18 cm.
• Area of triangle = 18 cm².

Explanation:

⋆ Given:

• Base of triangle = 6 cm
• Height of triangle = 6 cm
• Sides of triangle = 5 cm, 6 cm and 7 cm.

⋆ To Find:

• Perimeter of triangle.
• Area of triangle.

⋆ Formula used:

• Perimeter of triangle = Sum of all 3 sides.
• Area of triangle = 1/2 × Base × Height

Now, firstly we will find perimeter of triangle,

➯ Perimeter of triangle = Sum of all 3 sides.

➯ Perimeter of triangle = 5 + 6 + 7

➯ Perimeter of triangle = 18 cm

Hence, Perimeter of triangle = 18 cm.

Now, we will find area of triangle,

➯ Area of triangle = 1/2 × Base × Height

➯ Area of triangle = 1/2 × 6 × 6

➯ Area of triangle = 3 × 6

➯ Area of triangle = 18 cm²

Hence, Area of triangle = 18 cm².
