Answer 1

Answer:

1)13cm

2) 25cm

3) 50m

Step-by-step explanation:

1) perimeter=35

sides=10 and 12

10+12=22

35-22=13

so the third side is 13 cm

2) sides=9,9,7

perimeter formula =2a + b

9+9+7=25

so the perimeter is 25 cm

3) a square has four sides so

perimeter/4

200/4

=50

so the square side is 50 metre
