Find the total area for the regular pyramid

T. A =

4 + 4sqrt(10)

Step-by-step explanation:

TA = square + 4(slant triangles)

Area of square = 2² = 4

Use pythagoras theorem to find the slant height 'h':

h² = 3² + 1²

h² = 9+1 = 10

h = sqrt(10)

Area of a triangle = ½×2×sqrt(10)

= sqrt(10)

TA = 4 + 4(sqrt(10))

TA = 4 + 4sqrt(10)

sqrt: square root

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
