Question 5
The base of a triangle is 12 cm and height is 5 cm then area of triangle will be :
(A) 30 sq. cm
(B) 60 sq. cm
(C) 120 sq. cm
(D) 28 sq. cm

Answer 1

Answer:

30 cm²

Step-by-step explanation:

Given :

Base of triangle = 12 cm

Height of triangle = 5 cm

We know :

Area of triangle = 1 / 2 × Base × Height

Area of triangle = 1 / 2 × 12 × 5 cm²

Area of triangle  = 6 × 5 cm²

Area of triangle = 30 cm²

Answer 2

Question :

The base of a triangle is 12 cm and height is 5 cm then area of triangle will be :

(A) 30 sq. cm

(B) 60 sq. cm

(C) 120 sq. cm

(D) 28 sq. cm

Solution:

$\underline{\bold {Given:}}$

• The base of the triangle = 12 cm
• The height of the triangle = 5 cm

$\underline{\bold {To\:Find:}}$

• The area of the triangle.

$\boxed{\purple{Area=\frac{1}{2} \times base \times height}}$

$\implies Area=\frac{1}{2} \times base \times height \\ \implies Area = \frac{1}{2} \times 12 \: cm \times 5 \: cm\\\implies Area = 6 \: cm \times 5 \: cm \\ \implies Area = 30 \: sq.cm$

$\boxed {\green {\therefore{The\: area\:of\:the\:triangle\:is\:(a)30\:sq.cm.}}}$
