The perimeter of an office whose floor area is 225 square units is 60 units
For example;
For example;
We are given the area of a square as 225 square units
Therefore; since the area of a square is given as s², where s is the side of the square.
Then; s² = 225
s = √ 225
= 15 units
But Perimeter of a square is given by; 4 × s
Thus; Perimeter = 4 × 15 units
= 60 units

Answer: negation.
Step-by-step explanation: In a triangle, all angles cannot be right angles, because if it is so, then 90°+90°+90°=270°>180°. Hence, not possible. Also, a triangle has only three sides, so the sentence that a triangle has four sides is also not correct.
So, the given statement is a combination of two negative statements, and so, it is negation.
Thus, the correct answer is negation.
The range for the measure of the third side of the triangle is (5, 38).
A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
Given that,
Two sides of the triangle are 18 ft and 23 ft.
Let the third side of the triangle is x cm.
Since, the third side is greater than the difference of the remaining sides and less than the sum of the two sides.
Implies that,
23 - 18 < x < 23 + 18
5 < x < 38
The range of the third side varies from (5, 38).
