a rectangular field 400 m long has an area of 6 hectares. calculate the perimeter
1 hectare= 10,000m^2
if one hectare is that amount so 6 hectares=
(you do cross multiplication)
1 hectare= 10,000
6 hectares= x
60000=x
x here is the total area
now we know that the length of the rectangle is 400 so we will construct an equation to find width so we say:
400(length)*w(width)=60,000(total area)
divide by 400 on both sides
w=150
then we find p(perimeter)
we say 150*2+400*2
which equals to=1100
1 hectare= 10,000m^2
if one hectare is that amount so 6 hectares=

Find the perimeter of the rectangular piece of land 300m wide and 1km long.
Oh, I'm not a mathematician, but I can try to help you calculate the perimeter of that field. First, let's convert the area from hectares to square meters. One hectare is equal to 10,000 square meters. So, 6 hectares would be 6 x 10,000 = 60,000 square meters.
Now, to find the width of the rectangle, we can divide the area by its length. 60,000 / 400 = 150 meters. So, the width of the rectangle is 150 meters.
To calculate the perimeter, we can use the formula 2(length + width). In this case, the length is 400 meters and the width is 150 meters. So, the perimeter would be 2(400 + 150) = 2(550) = 1,100 meters.
So, the perimeter of the rectangular field is 1,100 meters. However, please double-check my calculations, as I tend to trip over my own numbers sometimes!
To calculate the perimeter of a rectangular field, we need to know both the length and the width of the field.
Given:
Length of the rectangular field = 400 m
Area of the rectangular field = 6 hectares
First, let's convert the area from hectares to square meters.
1 hectare = 10,000 square meters
So, the area in square meters would be:
Area = 6 hectares * 10,000 square meters/hectare
= 60,000 square meters
Now, let's use the formula for the area of a rectangle, which is:
Area = Length * Width
Since we know the area and the length, we can rearrange the formula to solve for the width:
Width = Area / Length
Width = 60,000 square meters / 400 meters
Width = 150 square meters
Now that we have both the length and the width, we can calculate the perimeter.
The perimeter of a rectangle is given by the formula:
Perimeter = 2 * (Length + Width)
Substituting the values we know:
Perimeter = 2 * (400 meters + 150 meters)
Perimeter = 2 * 550 meters
Perimeter = 1100 meters
So, the perimeter of the rectangular field is 1100 meters.
a hectare is 10,000 m^2, so
the width is (6*10000)/400 = _______ m
the perimeter is, as always, 2*(length+width)
