2*(40 + 8) = 2*48 = 96 cm.
26cm
Perimeter= 2length x 2widthSince the perimeter is 40 and 2 times the width is 16, that means 2 times the length is 24. The length is 12.
Perimeter is the total of all the sides. Let's assume your part-question relates to a rectangle. Four sides: 2 x 8cm and 2 x 15cm. I'm sure you can work it out from there...
42cm
Two sides of 8cm & two sides of 3cm fit the problem. 8+8+3+3=22cm (the perimeter you stated) AND a rectangle of 8x3cm is an area of 24cm2
A rectangle that is 2cm by 4cm has an area of 8cm. It also has a perimeter of 12cm.
64cm (8cm x 8 sides = 8 x 8 = 64).
P = 48cm
if you mean a rectangle: 8x2=16, that is 2 sides. 28-16=12cm 12/2 = 6cm so 8cmx6cm, if it is a rectangle
perimeter = 8+8+5+5 = 26cm
Width of rectangle: 144/18 = 8cm Perimeter of rectangle: 2*(18+8) = 52cm
Perimeter = 4 * side = 4* 8 = 32cm
