Their ages are jan's age = 19 and tritts age be 11 yaers
What is Algebra?
Algebra is a branch of mathematics that deals with symbols and the arithmetic operations across these symbols. These symbols do not have any fixed values and are called variables. In our real-life problems, we often see certain values that keep on changing. But there is a constant need to represent these changing values.
Given:
Jan's Age is 3 years less than twice Tritts age.
sum of their ages is 30.
let tritts age be x
jan age= 2x -3
Now, sum of their ages = 30
x+ 2x-3 = 30
3x= 33
x=11
hence, jan's age = 19 and tritts age be 11 yaers

3x-3=30
3x=33
Tritts age=x=11
Jans age=2x-3=2(11)-3=22-3=19
Tritt=11
Jan=19

The surface area of the pyramid is calculated by the formula B +(1/2) *P*L.
What is a Regular Pyramid?
A regular pyramid is a three dimensional structure with a regular polygon base and all the lateral surfaces are equal.
The surface area of a Regular Pyramid is the sum of the area of the base and the area of the lateral surface.
Surface area of Pyramid = Area of base + Lateral surface area of the sides
Surface area of Regular Pyramid = B +(1/2) *P*L
Here P is the perimeter of the base and L is the slant height, B is the area of the base.
Therefore, the surface area of the pyramid is calculated by the formula B +(1/2) *P*L.

The lateral surface area of a regular pyramid is the sum of the areas of its lateral faces. The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base. The general formula for the lateral surface area of a regular pyramid is where p represents the perimeter of the base and l the slant height. Example 1:Find the lateral surface area of a regular pyramid with a triangular base if each edge of the base measures 8 inches and the slant height is 5 inches.The perimeter of the base is the sum of the sides.p = 3(8) = 24 inchesThe general formula for the total surface area of a regular pyramid is where p represents the perimeter of the base, l the slant height and B the area of the base. Example 2:Find the total surface area of a regular pyramid with a square base if each edge of the base measures 16 inches, the slant height of a side is 17 inches and the altitude is 15 inches.The perimeter of the base is 4s since it is a square.p = 4(16) = 64 inches The area of the base is s2.B = 162 = 256 inches2T. S. A. = There is no formula for a surface area of a non-regular pyramid since slant height is not defined. To find the area, find the area of each face and the area of the base and add them.
