Answer 1

Answer:

so , now you have to find the sum of [using laptop can't take picture]

Step-by-step explanation:

40m+96m= 136m(0.136)

therefore, the perimeter of the 3rd square is 136m.

Answer 2

Hi friend,

here is your answer

please follow me

Answer:

perimeter of first square equal = 40 m

so, the side of the first square will be 40/4 = 10m

hence, the area of the first square is 10^2 = 100m^2

perimeter of the second square = 96 m

so the side of the second square will be 96/4 = 24m

hence the area of the second square is 24^2 = 576m^2

now, the area of third square equal to sum of the area of first square and second square

so, the area of third square = 100 + 576 = 676m^2

the side of the third square = √676 = 26m

so, its perimeter will be 26 × 4 = 104m

hope it helps you and you understood
