Answer:
- Width = 10cm
- Perimeter = 60 cm
Step-by-step explanation:
a. Width
We are given the area and the length so we can use this to find the width using the formula for rate:
Length * Width = Area
20 * w = 200
20w = 200
w = 200/20
w = 10 cm
b. Now that you have both the length and the width, the perimeter is:
= (2 * length) + (2 * width)
= (2 * 20) + (2 * 10)
= 40 + 20
= 60 cm
