Answer:
A = 225 m ^2
Step-by-step explanation:
The perimeter of a square is found by
P =4s where s is the side of a square
60 = 4s
Divide each side by 4
60/4 =4s/4
15 = s
Now we need to find the area
A = s^2 for the area of a square
A = 15^2
A = 225 m ^2
<h3>
Answer: 20 cm, 35 cm, and 50 cm</h3>
=========================================================
Explanation:
The sides are in the ratio 4:7:10
This scales up to 4x:7x:10x showing that the sides are 4x, 7x and 10x. The variable x is some positive real number.
Add up the sides and set this equal to the given perimeter 105. Solve for x.
4x+7x+10x = 105
21x = 105
x = 105/21
x = 5
This value is then plugged into each side
- 4x = 4*5 = 20
- 7x = 7*5 = 35
- 10x = 10*5 = 50
The triangle has sides of 20 cm, 35 cm, and 50 cm.
Note how the ratio 20:35:50 reduces to 4:7:10 after dividing all three parts by the GCF 5. Also, we can see that 20+35+50 = 105 to fully confirm our answer.
The answer is a, proportional.
