Question

Find altitude of triangle if base is 12cm and area is 48 cm square

Answer 1

Answer:

$\large{\underline{\boxed{\sf Altitude = 8 \: cm}}}$

Step-by-step explanation:

Given that ;

Base of triangle = 12 cm

Area of triangle = 48 cm²

To find;

The altitude of triangle.

Solution:

We know that ;

Area of triangle = $\bf \dfrac{1}{2 }$ * base * altitude

⇒ 48 = $\sf \dfrac{1}{2}$ * 12 * altitude

⇒ 96 = 12 * Altitude

⇒ Altitude = $\sf \dfrac{96}{12}$

⇒ Altitude = 8 cm

Hence, the altitude of the triangle is 8 cm.

Answer 2

Answer:

$\huge{\red{\boxed{\boxed{\green{\sf{\therefore ALTITUDE=8cm}}}}}}$

Step-by-step explanation:

$\huge{\red{\boxed{\boxed{\green{\underline{\red{\sf{SOLUTION-}}}}}}}}$

${ \green{\boxed{area = 48 {cm}^{2} }}} \\ {\green{ \boxed{base = 12cm}}} \\{\red{\boxed{Altitude=?}}}\\ \\ > > according \: to \: the \: question \\ \\ Area \: of \: triangle = \frac{1}{2} \times base \times height \\ = ) 48 {cm}^{2} = \frac{1}{2} \times 12 \times h \\ = )48 = 6 \times h \\ = )h = \frac{48}{6} \\ = )h = 8cm$

$\huge{\red{\boxed{\boxed{\green{\sf{\therefore ALTITUDE=8cm}}}}}}$
