Answer 1

Answer:

Step-by-step explanation:

Answer 2

Step-by-step explanation:

let side of first square be x

perimeter = 40 cm

4 x = 40

x = 10 cm

area = x * x = 10 * 10 = 100 cm sq.

let side of second square be y.

perimeter = 32 cm

4 y = 32

y = 8 cm

area = y*y = 8 * 8 = 64 cm sq.

area of third square = 100 - 64 = 36 cm sq

let side of third square be z

z*z = 36

z = 6 cm

perimeter of third square = 4* z = 4*6= 24cm
