Answer:
100cm
Step-by-step explanation:
So you will need to find both The length and width. They have already given you the width so now you need to find the length based on the instructions they gave you.
Width=10cm
Length=__cm
so the length is 4 times its width. 4 times mean you will just multiply the width 4 times.
10x4=40
so the length is 40cm
Width=10cm
Length=40cm
Now we need to find the perimeter. The perimeter is the total length around the shape. So because a rectangle has 2 sides that are the width and 2 sides that are the length, you will multiply the length and width by two:
10x2=20
40x2=80
now you add them up to find the total permeter which is 100cm
