2(length+breadth)=Perimetre Length= (Perimetre/2)-Breadth Area=Length x breadth
You measure the sides of the shape you are finding the perimetre of and then add together the measurements. Then you have your answer. eg: 8cm x 7cm x 3cm x 5cm 8+7+3+5=23 answer is 23cm
The area of a square that has a perimeter of 32m is: 64 m2
I don't understand why there are so many questions about rectangles' perimeter. You just add the length and the width and double your answer....
i dont know
It is: 3*20 = 60 cm
length plus width equals perimetre
^Perimetre. Outer length of a shape.
Perimetre of squre is 4*(side) and side is 8 cm so perimetre is 4*8=32cm
4 times the length of its side.
2(length+breadth)=Perimetre Length= (Perimetre/2)-Breadth Area=Length x breadth
It is the sum of its 4 sides added together
this is stupidinuss
216 cm
28 cm
1/2*perimetre of base*slant height
Add up together its 4 sides
