Answer:
Area = 45 m²
Step-by-step explanation:
We have given that
The length of the rectangle is 4m longer than its width.
Let l be the length and w be the width.
w = l+4
The perimeter is 28m
Perimeter = P= 28
The formula for perimeter is:
P = 2l+2w
28 = 2l+2(l+4)
28 = 2l+2l+8
28-8 = 4l
20 = 4l
l = 5 m
hence, w = 5m+4m
w = 9 m
The formula to calculate area of rectangle is:
Area = A = Length × width
Area = 5 × 9
Area = 45 m² which is the answer.

Answer:
3.186 x 10^8
Step-by-step explanation:
3.2× 10^8 = 320,000,000
1.4 × 10^6 = 1,400,000
320,000,000 - 1,400,000 = 318,600,000
318,600,000 = 3.186 x 10^8
- you get to the power of eight, by counting the amount of spaces the decimal moved over (moving to the left increase, but right decreases)
Answer:
total number of sheep in the farm = 28 6 = 168
Step-by-step explanation:
i) let the number of all sheep in the farm be x.
ii) 28 sheep were tagged.
iii) 18 sheep were observed and 3 were found to be tagged.
Therefore the ratio of tagged to sheep to the number of sheep observed
=
iv) therefore we can apply the ratio found in iii) as follows
∴ total number of sheep in the farm = 28 6 = 168
