will fan and metal PLZ HELP!!! Cole drew a rectangle that is 3 meters by 10 meters. It has an area of 30 square meters and a perimeter of 26 meters. Which rectangle has dimensions that give the same perimeter as Cole's rectangle, but has a different area? A. 15 meters by 2 meters B. 7 meters by 6 meters C. 5 meters by 6 meters D. 2 meters by 13 meters
so perimeter of a rectangle is determined by 2w+2h, in this case it is 2h+2w= 26 which of these options fits
so whats the awnser i cant do this its to hard and this is my last one just need an awnser
but i am reading and it starts to make sence
so can you plz help me out @Brill
Just guess and check, multiply each of the height and width by 2, then add them together and see if they add up to 26
For example I'll try option A... The height and width are 15 and 2, so 15x2= 30 and 2x2=4.... 30+4=34 So that isnt the right answer
Just repeat that proccess
ok
i thinks its c because like my brothers are ting to help
and they cant
Ok so let's try what I said to do with C 5x2=10 6x2=12 10+12=22
So that isnt the right answer
keep trying
ok
what about b
Yep Because 7x2=14 and 6x2=12 14+12=26
Good job :D
YES thank you so much <3
