$200
Step-by-step explanation:
125/5=25
25 x 8=200
Answer:
Yes, this set of lengths can form a triangle.
Step-by-step explanation:
55+76 = 131
131 > 112
Since the sum of smaller lengths is greater than 112, these numbers can form a triangle.
Answer:
y = 6.5 units
Step-by-step explanation:
Let L be the length of sides of the square.
Given the following data;
Perimeter of square = 8y - 12
Area of square = 100 square units
To find the value of y;
Area of a square = L²
Substituting into the formula, we have;
100 = L²
L = √100
L = 10 units
Mathematically, the perimeter of a square is given by the formula;
Perimeter of a square = 4L
Substituting into the formula, we have;
8y - 12 = 4*10
8y - 12 = 40
8y = 40 + 12
8y = 52
y = 52/8
y = 6.5 units
