Bianca needs to paint a logo made using two right triangles. The dimensions of the logo are shown below. What is the difference between the area of the large triangle and the area of the small triangle?

Two right triangles are attached along their longest side. The smaller triangle has height 6 cm and base 2 cm. The height of the larger triangle is 7 cm and its base is 3 cm.

OK.....you do not seem to be learning any of this material.....many of your many questions are very similar and require similar thinking and formulas.....TRY to get an answer THEN ask for help.....

Triangle area = 1/2 base * height      You SHOULD be able to answer the question with this bit of info....TRY!cheeky  You learn NOTHING by only looking for answers!

The area of a triangle is 

\(Base * Height * \frac{1}{2}\) 

 

 

so for the smaller triangle we have 

 

\(2cm * 6cm *\frac{1}{2}\) 

equals

6 cm squared 

 

The second triangle is 

\(3cm * 7cm * \frac{1}{2}\) 

equals 

\(10 \frac{1}{2}\) 

squared inches and the diffrence is subtracting the smaller traingle from the bigger one whih equals 

\(4 \frac{1}{2}\)

Small is

You are getting there:

   You forgot the 1/2 part     triangle area = 1/2*  base * height

 

The difference is 'How much bigger is the larger than the smaller?'   DOes that help?

12 divided by 1/2 is 6 

 

and 

 

21 divided by 1/2 is 10.5  I belive it is 

 

and the difference is 

4.5
