I BEG YOU TO HELP ME PLEASE !!!!!

I have got a maths test for tomorrow and I can't do two exercices. Please help me.

 

Here's one of them :

There's a drawing of a triangle and a smaller one inside it but I can't insert it. I don't thinK it matters too much as its not exact.

Theres the three summets, R, P AND Q then in the smaller triangle there's three summets U, T AND S. P, S an U are all on the same line sme as Q,T,S and T,U,R. TQ=1/2ST UR=1/3TU SP=1/4SU. We know that the air of the smaller triangle SUT is 5cm².

CALCULATE THE AREA OF THE TRIANGLE PQR.

 

PLEASE HEEEELP !

Does it tell you what type of triangles they are?

 

Silver an Freddie can sort this one:wink2:

 

Ill get some paper and a pen

 

Me!:shocked: I'm hopeless at maths :roftl: I was just trying to work out what the thing looked like.

 

I had some vague idea of trying to work out the areas of the individual triangles, if only I could remember the formula for doing it.

Yeh if we can see it , it really helps , all I can piture is A , Z , P , Q and letters

 

Your right there will be a formula for it :thumb_yello:

Have you learnt a formula for working out the area of a triangle?

 

errrm ... maybe, I really dunno Ive forgotten. If you tell me Id remember but like that ... :blink: Im ****ty in maths :thumbdown:

 

Just in general and me working backwards :naughty:

 

I think the length of each side is 3.4cm

Actually Im thinking the LARGE triangle is equilateral now ....

 

is that good or bad ?

Sur la figure ci-dessous qui n'est pas a l'echelle = on the figure below which isn't exact,

les points P,S,U sont alignes = the pints P,S And U are aligned (in one straight line)

ainsi que Q,T,S et ,T,U,R= aswell as Q,T,S and,TU,R

on sait que l'aire du triangle STU est 5cm² = we know that the area of the triangle STU is 5cm²

CALCULER L'AIRE DU TRIANGLE PQR = calculate the area of the traingle PQR

thats all :boxed:
