Answer:

17

Step-by-step explanation:

Assuming the field is a rectangle, the perimeter is found through the equation:

P = 2l + 2w

Since we know the perimeter and width, we can substitute and solve for the length.

(220) = 2l + 2(62)\\220 = 2l + 124\\96 = 2l\\l = 48\\

Using the length and width, we can find the area.

A = lw\\A = (48)(62)\\A = 2976

The area is 2976 squared meters. We divide by the area a bag of canola seed can cover and round up if necessary to find the total number of bags.

n = 2976 / 185\\n = 16.09

Because we need a whole bag in order to cover for the decimal area, we round up to 17 bags.

PLEASE HELP ASAP I’LL MARK BRAINLIEST Find the area of the figure.
Sonbull [250]
Area of a semicircle is 1/2* πr^2
Area of a square is s^2


Square’s area: 4mm^2

The radius is 3mm
Plug into the equation

1/2* π(3^2)
1/2* π(9)

We can use 3.14 as an estimate of pi

1/2*28.26

14.13mm^2

Now just add them both

Total area 18.13mm^2

A population of rabbits triples every month.the population starts with two rabbits.how many rabbits are there after 3 month's
Tresset [83]
The answer would be 54. Because you start with 2.
2x3 = 6
6x3 = 18
18x3 = 54
Each month it triples so you continue
to add 3 to each result.

Answer:

42m

Step-by-step explanation:

First we need to find the base, which is 6 and the height which is 7. Then, multiply 6 and 7 to get 42. Then add your units, which are meters. So, 42m is your answer. I hope this helps! :)
