Answer:
120
Step-by-step explanation:
Each fourth of the rhombus is equal, so when we find the area of 1 triangle, we can find the area of the entire shape.
The formula for the area of a triangle is 1/2(b*h).
In this case, b=5 and h=12.
5*12=60
60*(1/2)=30
Now that we've found 1/4, lets multiply by 4 to find the total.
30*4=120
Therefore, the answer is 120
Answer:
= (n + 1)²
Step-by-step explanation:
The terms are square numbers with each term shifted to the right by 1
That is 1, 4, 9, 16, 25, 36, .....
Thus to obtain 4 in the first position, then
n = 1 → (1 + 1)² = 2² = 4
To obtain any term add 1 to its position in the sequence, that is
= (n + 1)²

See explanation. I added a photo and tried to explain everything. Please tell me in the comments if I explained it well and if handwriting was ok :)
Step-by-step explanation:
yes
10² = 10 × 10 = 100
divide 100 by her daily average of 20
= 5
