Question

find the area of a triangle of base 12 cm and height 1.5 cm ​

Answer 1

Step-by-step explanation:

Answer :-

• Area of the triangle = 9 cm

Question :-

• Find the area of a triangle of base 12 cm and height 1.5 cm.

Solution :-

${\boxed{ \underline \pink {\sf\: We \: know \: that \: Area \: of \: a \: triangle \rightarrow \bf \: \dfrac{1}{2} \times base \times height}}}$

$\implies \: \sf \: Area \: of \: the \: triangle \rightarrow \dfrac{1}{ \cancel2} \times \cancel{12\: cm }\: \times 1.5 \: cm$

$\implies \: \sf \: Area \: of \: the \: triangle \rightarrow 1 \times 6 \: cm\: \times 1.5 \: cm$

$\implies \: \sf \: Area \: of \: the \: triangle \rightarrow 9 \: cm$

${\huge \therefore}\: \sf \: Area \: of \: the \: triangle \bf \bf \bf \rightarrow 9 \: cm$

Answer 2

Answer:

Hence, area of triangle will be 9 sq. cm

Step-by-step explanation:

In context to question asked,

We have to determine the area of triangle.

As per question,

We have,

Base of triangle = 12 cm

Height of triangle = 1.5 cm

As we know that,

We have formula for finding the area of triangle.

As we have,

$Area = \frac{1}{2}\times b \times h$

So, for determining the value of area of triangle, we will put the value of base and height in above formula,

Thus we will get,

$Area = \frac{1}{2}\times 12 \times 1.5\\=>\frac{18}{2} = 9\:cm^2$
