Question

If base and height of a triangle is 12 m and 17 m respectively, then the area of triangle is (A) 102 m (B) 58 m (C) 204 m (D) None of these​

Answer 1

Given : Base and Height of a triangle are 12 m and 17 m .

To Find : Find the Area of Trangle

$\\ \qquad{\rule{200pt}{2pt}}$

SolutioN : For solving this question we need to apply the formula for Area of Triangle . Let's Solve :

$\maltese$ Formula Used :

• ${\underline{\boxed{\pmb{\sf{ Area{\small_{(Triangle)}} = \dfrac{1}{2} \times Base \times Height }}}}}$

$\maltese$ Calculating the Area :

$\qquad {\dashrightarrow{\qquad{\sf{ Area = \dfrac{1}{2} \times Base \times Height }}}} \\ \\ \\ \ {\dashrightarrow{\qquad{\sf{ Area = \dfrac{1}{2} \times 12 \times 17 }}}} \\ \\ \\ \ {\dashrightarrow{\qquad{\sf{ Area = \dfrac{12}{2} \times 17 }}}} \\ \\ \\ \ {\dashrightarrow{\qquad{\sf{ Area = \dfrac{204}{2} }}}} \\ \\ \\ \ {\dashrightarrow{\qquad{\sf{ Area = \cancel\dfrac{204}{2} }}}} \\ \\ \\ \ {\qquad \; \; {\dashrightarrow{\underline{\boxed{\pmb{\sf{ Area = 102 \; {m}^{2} }}}}}}} \; {\pink{\bigstar}}$

$\therefore \; \;$ Area of the Triangle is 102 m² .

Answer 2

Answer:

A) 102 m

Step-by-step explanation:

firstly,base= 12m and height= 17m

then we will use the formula of area of triangle i.e.

Area= 1/2×base×height

= 1/2×12×17

= 6×17

= 102 m
