Answer 1

Question :

Find the length of the base of a triangle whose area is 440m² and altitude is 11m .

Answer :

$\bf\pink{Given:}$

• Area of a triangle is 440 m² .

• Height of the triangle is 11 m .

$\bf\pink{To\:find:}$

• Base of the triangle ?

Explanation :

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

• b means base .

• h means height .

$\\ \longrightarrow\sf{ 440 = \dfrax{1}{2}\times b\times 11}$

$\\ \longrightarrow\sf{ 440\times 2 = 11b}$

$\\ \longrightarrow\sf{ 880 = 11b}$

$\\ \longrightarrow\sf{b = \dfrac{880}{11}}$

$\\ \longrightarrow\sf{b = 80}$

Therefore the base is 80 m .
