Compute for the perimeter of each of the following rectangle:

Question

1. 20 meters long 10 meters wide
2. 50 meters long 30 meters wide
3. 80 meters long 40 meters wide

Answer 1

1. The perimeter of the rectangle with a length of 20 meters and a width of 10 meters is computed as follows:

Perimeter = 2(length + width)
= 2(20 + 10)
= 2(30)
= 60 meters

So, the perimeter of the rectangle is 60 meters.

2. The perimeter of the rectangle with a length of 50 meters and a width of 30 meters is computed as follows:

Perimeter = 2(length + width)
= 2(50 + 30)
= 2(80)
= 160 meters

So, the perimeter of the rectangle is 160 meters.

3. The perimeter of the rectangle with a length of 80 meters and a width of 40 meters is computed as follows:

Perimeter = 2(length + width)
= 2(80 + 40)
= 2(120)
= 240 meters

So, the perimeter of the rectangle is 240 meters.
