Clear, fast and with no wasting time. No unecessary calculations. Perfect solution.
Cool, I didn't think of that answer and I thought there was too little information!
Incognitas horizontales: (a); (a+b=7); (c) → 5+b+a=5+7=12=c+a
Incognitas verticales: (d); (e); (f) → d+e+f=9
Perímetro de la figura: 2*12+2*9=24+18 =42.
Gracias y saludos.
Great video
The thumbnail with the dotted line is misleading. It makes it seem like its 7 from the dotted like to the end.
the heck man approach: so there are 50 little backround sqares touching the known side lengths , 9+5+7 is 22 so divide 50 by 22 and to get 2.2727
there are 100 little backround squares around the whole perimeter
divide 103 by 2.2727 to get 45.32
my not be perfect but if its a multiple choice question dont know what your doing the heck man approach worh a shot😁👍
X=3 perimeter is 42
Why is x equals 3? X can be zero.
There's no sufficient info to calculate X it could be anything from 0 to 5. Same thing can be said about the area. The perimeter however stays constant regardless of X value as it's adding X to the perimeter but at the same time subtracting X from the length of the bottom side, nullifying its effect!
