How would I do this and work it out ? Only 15-17 please help me !!

u need to find the square root, I hope u can understand I'm really bad at explaining

Step-by-step explanation:

so the symbols around the number means square root of...I'll give u an example

square root of 4

so 2×2=4, the square root has to be the same number like 2 and 2

if u need to find the square root u can multiply the numbers such as..

1x1

2x2

3x3

4x4

5x5

6x6

7x7

8x8

9x8 etc.

unlit u find the square root of any number. if u find the closest number but it's not quite the square root u can use decimals as well!

as I said I am terrible at explaining so let me know if u need any clarification

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
