Question

The Base of the Triangle is 900 cm² and its height is 90 m find the Base.​

Answer 1

Given :

• Area = 900 cm²
• Height = 90 cm

To Find :

• Base = ?

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

SolutioN :

☆ Formula Used :

• Area(Triangle) = 1/2 × Base × Height

☆ Calculating the Base :

$\begin{gathered} \qquad \; :\longmapsto \; \; \sf { Area = \dfrac{1}{2} \times Base \times Height } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; :\longmapsto \; \; \sf { 900 = \dfrac{1}{2} \times Base \times 90 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; :\longmapsto \; \; \sf { 900 \times 2 = 1 \times Base \times 90 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; :\longmapsto \; \; \sf { 1800 = Base \times 90 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; :\longmapsto \; \; \sf { \dfrac{1800}{90} = Base } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; :\longmapsto \; \; \sf { \cancel\dfrac{1800}{90} = Base } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; :\longmapsto \; \; {\underline{\boxed{\pmb{\sf { Base = 20 \; cm }}}}} \; {\red{\pmb{\bigstar}}} \\ \\ \\ \end{gathered}$

☆ Therefore :

Base of the Triangle is 20 cm .

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