Question

What is the area? write your answer as a fraction or as a whole or mixed number

Answer 1

$\underline \mathcal \pink{ GIVEN}$

• Base = 2 9/10 km
• Height = 4 6/7 km

$\underline \mathcal \purple{ TO \: FIND}$

• Area of the triangle

$\underline \mathcal \blue{CALCULATION}$

$\qquad \tt \leadsto \: area = \frac{1}{2} \times base \times height$

$\qquad \bf \nrightarrow \: area = \frac{1}{ \cancel2} \times \cancel2 \frac{9}{10} \times 4 \frac{6}{7}$

$\qquad \bf \nrightarrow \: area = \frac{9}{ \cancel{10}} \times \cancel4 \frac{6}{7}$

$\qquad \bf \nrightarrow \: area = \frac{9}{ 5} \times 2 \frac{6}{7}$

$\qquad \bf \nrightarrow \: area = \frac{108}{ 35} \approx3.08 \: {km}^{2}$

Thus, The area of the triangle is 3.08 kilometers...~
