Answer:

The length of each side of the triangle is 6.5 cm

Step-by-step explanation:

Perimeter of a triangle (p) = 2a + b

where a = length of side

b = base of the triangle

p = 20 cm

b = 7 cm

p = 2a +b

20 = 2a + 7

2a = 20 - 7

2a = 13

a = 13 /2

a = 6.5

a = 6.5 cm

since it is an isosceles triangle, the two sides are equal = 6.5 cm
