Area = Length * Width
.
400 = L * 16
.
L = 25
.
Perimeter = 2L + 2W
.
P = 2(25) + 2(16)
.
P = 82 m

what is the perimeter of a rectangle that has an area of 400 square meters and a width of 16 meters?
.
To find the perimeter, we need the length and width of the rectangle. They give us only the width but they also give us the area. From the area, we can find the length:
.
Let x = length of rectangle
then
16x = 400
x = 400/16
x = 25 meters
.
Perimeter = 2(length+width)
Perimeter = 2(25+16)
Perimeter = 2(41)
Perimeter = 82 meters

What is the perimeter of a rectangle that has an area of 400 square meters and a width of 16 meters?

Step 1. The perimeter P means adding up the four sides of the rectangle.

Step 2. The Area A=400. Let x be the length or x=400/16=25

Step 3. Then, P=16+16+25+25=82 meters

Step 4. ANSWER: The perimeter is 82 meters.

I hope the above steps were helpful.
