Please do step by step and I’ll BRAINLIEST YOU!!!! Do what you can please!

Answer 1

Answer:

Ans 5)

let the side of the square be x

ATQ

area = 676 $m^{2}$

$x^{2} = 676\\\\x = \sqrt{676}\\\\x = 26 m$

therefore side is 26 m

Ans 6)

let the side of the square be y

ATQ

perimeter = 4y

area = 3969 $m^{2}$

$y^{2} = 3969\\\\y = \sqrt{3969}\\\\y = 63 m$

thus perimeter = 4 * 63 m = 252 m

Ans 7)

we know that the LCM of 12 & 16 is 2 * 2 * 2 * 2 * 3

and we also know that each number in a square comes twice

thus the smallest square divisible by 12 & 16 is "2 * 2 * 2 *2 * 3 * 3 " = 144

Ans 8)

total number of students = 2116

let the number of rows be x

ATQ

number of rows = number of columns

i.e number of columns = x

now if we multiply number of rows and number of columns we will get the total number of students in the drill

therefore

$x * x = 2116\\\\x^{2} = 2116\\\\x = \sqrt{2116}\\\\x = 46$

therefore 46 rows & columns will be made for arranging the students in the drill display

sorry didn't knew Ans 3 & 4
