Question

Please answer questions 1 and 2 ASAP

Answer 1

Answer:

1. Perimeter= 40 cm

a = 12.9 cm

b = 14.6 cm

Perimeter =a+b+c

40=12.9+14.6+c

40 = 27.5 +c

c +27.5 = 40

c = 40 -27.5

c = 12.5 cm

2. Perimeter = a+b+c

a = 14 cm

b=17 cm

c=25 cm

Perimeter = 14 +17+25

Perimeter = 56 cm

I hope this will help u mate

Answer 2

Answer:

a+b+c= perimeter of triangle

12.9+14.6+c = 40

27.5+c=40

c=40-27.5

c = 12.5

........................................................................

a+b+c= perimeter of

14+17+25=56

perimeter of is 56 units
