the width equals 14 cm. and the length equals 31 cm.
The length is 14 cm
You forgot to put in the length of the rectangle's perimeter.
length 18 width 7
150 cm
Perimeter of Rectangle = 2(length + width) =2(45+30) =150 cm
width=9 length=18
the width equals 14 cm. and the length equals 31 cm.
20 cm
12cm
The length could be 3 cm (width = 1 cm), with a perimeter of 8 cm, which is not more than 72 cm. Or it could be 6 cm (w = 2 cm, perimeter = 16 cm).
The length is 14 cm
You forgot to put in the length of the rectangle's perimeter.
length 18 width 7
700cm
Let the width of rectangle is w cm (Length is 12 cm more) so length is w + 12 Perimeter = 16 times of width 2 (length + width) = 16 * width Rest of the homework, do yourself.
150 cm
