Answer:

15cm

Step-by-step explanation:

because length is given as 8 cm and perimeter is length+width+length+width

so if you take 8cmX2 since its taken twice to get the perimeter and 15cmX2 you get 46cm which originally the question said was the peemiter

15cm

Step-by-step explanation:

The perimeter of a rectangle is P=2w+2L. (2 length)+(2width)

if the length is 8cm, then 2L will be 16 cm. 46=2w+16cm. We have 30 cm left which is the 2w. Divide 30cm by 2 to get w. W =15 cm.
