The length is 4 and width 15. When multiplied the area equals 60 and when you add up all the sides the perimeter is also 38.

The area of the triangle is found as 12 unit².
<h3>What is defined as the triangle?</h3>
A triangle is a three-sided polygon with three sides that closes a space.
- The three sides are formed by lines, line segments, or rays (in just about any combination).
- Three vertices, or corners, are formed if three sides form or meet.
- A triangle's height or altitude is calculated by drawing a perpendicular line through one side to the opposite angle.
- The base is the side with which the altitude intersects wherever it is built.
The formula for the area of the triangle is;
Area of triangle= ½ × base × height
The base is given as 6 units and the height is 4 units. (count 1 column of graph as 1 unit).
Put the values in formula.
Area of triangle = ½(6)(4)
Area of triangle = 12 unit.²
Therefore, the area of the triangle is found as 12 unit.²

Answer:
6 minutes
Step-by-step explanation:
'a' in the formula represents altitude in feet. You are told the altitude is 21000 feet, so put that into the formula:
21000 = 3400t +600
You can solve this for t:
20400 = 3400t . . . . . subtract 600 from both sides
6 = t . . . . . . . . . . . . . . . divide both sides by 3400
The problem statement tells you that t represents minutes after lift off, so this solution means the altitude is 21000 feet 6 minutes after lift off.
The question is asking for the number of minutes after lift off that the plane reaches an altitude of 21000 feet, so this answers the question directly:
The plane is at an altitude of 21000 feet 6 minutes after lift off.
