Answer 2

Given :

• Area of Triangle = 36 cm²
• Height of the Triangle = 3 cm

To find :

• Base/BC

Solution :

Let's know that,

$\sf Area \: of \: Triangle= \dfrac{1}{2} \times b \times h$

                    $\sf 36 = \dfrac{1}{2} \times b \times 3$

              $\sf Height = \dfrac{Area \times 2}{Base}$

              $\sf Height = \dfrac{36 \times 2}{3}$

              $\sf Height = \dfrac{72}{3}$

                         $\sf = 24$

Therefore, the height of the Triangle is 24 cm.

↣ Verifaction~

$\sf Area \: of \: Triangle= \dfrac{1}{2} \times b \times h$

                        $\sf = \dfrac{1}{2} \times 24 \times 3$

                        $\sf = \dfrac{1}{2} \times 72$

                        $\sf = \dfrac{ 72}{2}$

                        $\sf = 36$

Therefore, the Area of the Triangle is 36 cm².

• Hence, our answer is correct.
