What is the total area, in square units, of the four triangular faces of a right, square-based pyramid that has base edges measuring 6 units and lateral edges measuring 5 units

Given :

Square-based pyramid that has base edges measuring 6 units and lateral edges measuring 5 units.

To Find :

The total area, in square units, of the four triangular faces of a right.

Solution :

We know, area of square based prism is given by :

Here, a is the length of square base and h is the height .

Therefore, total area in square units is 51.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
