Question

. If base= 20 cm and height= 30 cm then find area of triangle. *
600 sq.cm
300 sq.cm
600 cm
300 cm

Answer 1

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Answer:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Given:

⠀⠀⠀⠀⠀⠀⠀⠀⠀

▪︎Base of triangle = 20cm

▪︎Height of triangle = 30cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀

To Find:

⠀⠀⠀⠀⠀⠀⠀⠀⠀

▪︎Area of triangle

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Solution:

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Area of triangle

$= ½ × base × height$

$= ½ × 20 ×30$

$= 300cm²$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Formula to be remembered:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\rightsquigarrow$Perimeter of triangle = Sum of all sides

$\rightsquigarrow$ Area of triangle = ½ × base × height

$\rightsquigarrow$ Area of triangle by Heron's formula of triangle

s = sum of all sides ÷ 2

$\sqrt{s(s-a)(s-b)(s-c)}s(s−a)(s−b)(s−c)$

Answer 2

Answer:

300 cm sq.

Step-by-step explanation:

Area of a triangle is = 1/2 × base × height

=1/2 × 20cm × 30cm

=1/2 × 600 cm^2

=600/2 cm^2

=300cm sq.
