Question

what will be the perimeter of triangle when base=4cm and height=3cm

answer with the formula

Answer 1

Appropriate Question :

• What will be the Area of triangle when base = 4cm and height = 3cm

Answer :

• Area of triangle is 6cm².

Given :

• Base of triangle is 4cm
• Height of triangle is 3cm.

To find :

• Area of triangle

Solution :

Finding the Area of triangle we have to use the formula of Area of triangle

Given,

• Base of triangle is 4cm
• Height of triangle is 3cm

We know that

• Area of triangle = ½ × b × h

Where,

• b is base of triangle
• h is height of triangle

Substituting the value :

↝ Area of triangle = ½ × b × h

↝ Area of triangle = ½ × 4 × 3

↝ Area of triangle = 2 × 3

↝ Area of triangle = 6cm²

Hence,

Area of triangle is 6cm².

Answer 2

Correct Question :-

➜ What will be the area of triangle when base is 4cm and height is 3cm

Given :-

➜ The base and height of a triangle is 4cm and 3cm

To Find :-

➜ What will be the area of triangle ?

Formula :-

➜ Area of the triangle = 1/2×b×h

Where,

• b = base
• h = height

Solution :-

Given that,

➞ The base of a triangle = 4cm

➞ The height of a triangle = 3cm

According to the question by using formula we get,

➡ Area = 1/2 × base × height

➡ Area = 1/2 × 4 × 3

➡ Area = 1 × 4 × 3 / 2

➡ Area = 12 / 2

➡ Area = 6

Hence,

∴ The area of a triangle is 6cm²
