Please help me someone

For the regular pyramid shown in picture:

Using Pythagorean theorem: L = sqrt((4/2)^2 + 11^2)

Lateral area = Area of one lateral face x 4 = (L x 4/2) x 4 = 89.4

The surface area = Lateral are + base = 89.4 + 4 x 4 = 105.4

Hope this helps!

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

multiple all that
