If you follow me, I can talk to you through PM.
Yes it helped understand Thanks A lot!!
Ooops, I made a slight error doing division in my head...For (B)...So, 2 * 84 cm^2 = 16 cm * h.168 cm^2 = 16 cm * h168 cm^2 / 16 cm = h10.5 cm = hThat is the correct answer.
For the second one you rotate the triangle and take 12 as the base. By taking 12 as the base, 14 becomes the height. So the area is 0.5×12×14= 84. Now we take 16cm as the base and find h. 0.5×16×h=848h=84h=10.5 cm.
For the last one take 24 cm as the base and 18cm as the height.0.5×24×18= an area of 216cmNow we take 20cm as the base to find h.0.5×20×h=21610h=216h=21.6cmThat was easy.
Thank you so much that was very helpful!! And a way easier method! For the second question is there a reason to rotate the triangle and take 12 as the base or is it just the method and there’s no reason for it?
We take 12 as the base for the second one so that we can use 14 as the height to calculate the area. 0.5xbase×height. Thats the formula for the area.

Thank you very much!
the trick often is to figure out one of the compound triangles first and then you can just substract the values that are given to know the infividdual lenths you're missing.
oh man just realized xD my typing is on point today :D you're welcome anyway :)
Maths, Topic: Perimeter and Area
Pm me and I can help
Unfortunately my Xp doesn’t allow me to Pm, as I have just started my account recently, is there a way you could still help me through here?
So the area is 0.5(base)(height).So some of these Triangles you could turn in a way to help you find a base and a height
Oh no I chose the wrong age group and there’s no way to edit it, I’m actually 16
ah ok sorry, maybe contact the head of dept/counsellor, sounds like your classmates aren't being very supportive, maybe there are voluntary tutors in your area that could help, I feel like you are being put down by classmates when they say they can't do it tbh, ex teacher here by the way,,,
is there maybe a maths club at your school?,
There was but with covid we do online school and there’s no more maths club unfortunately, I do my homework later in the day as it’s the best time suitable for me to do it so no maths teachers are usually online to help them
Yes I did :)
If you need any maths help, feel free to ping me. :)
Thank you I appreciate that I definitely will :)
You're quite welcome!
