Answer 2

Answer:

Step-by-step explanation:I

Let the third side be c

Perimeter = 154cm

Two sides are a = 48cm

b = 70cm

a+b+c = Perimeter

48+70+c = 154

118 +c = 154

c = 154-118

c = 36cm

Therefore the third side is 36cm

s = a+b+c / 2

s = 154/2

s = 77

Using Heron's Formula,Area of triangle =
