Two students explain the meaning of points (0,0) and (1,2).
• Kelvin says point (0,0) means the tank is empty when the inlet pipe is turned on.
• Paige says point (1, 2) means the water level of the tank goes up by 2 inches every minute.
Who is correct?
o both Kelvin and Paige
O neither Kelvin nor Paige
O only Kelvin

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
