Surface area is the area of the faces added together.

First lets find the area of one of the triangles.

Area of triangle is 1/2*base*hight

Area=1/2*2*3= 3

Area of ONE tringle is 3, and area of the FOUR tringles is 4*3 whihc is 12

Now lets find area of square

area of square is side*side

So, area is 2*2 which is 4

Now lets add area of triangles+area of square

12+4 which 16

Surface area is 16

If y varies directly as x and y = 12 when x = 8, find y when x = 14.
Alex17521 [72]
The direct variation between x and y may be written as,
                                    y = kx
where k is the constant of variation. From the first set of values of the variables,
                                 12 = k(8)
the value of k is 1.5. Substituting the next set to the same equation,
                                 y = 1.5(14) 
The value of y is 21.
