Question

the perimeter of an isosceles triangle is 44 CM the length of its congruent side is 4 cm more than its base find the length of all the sides​

Answer 1

Answer:

length of congruent sides = 40/3 cm. base = 14 cm

Step-by-step explanation:

perimeter of isosceles triangle = 44cm

let the congruent side be 'x' .

then the base will be 'x+4' .

2x + x + 4 = 44

3x + 4 = 44

3x = 44 - 4 = 40

x = 40/3 cm.

base = x + 4 = 40/3 + 4 = ( 40 + 12 )/3

= 52/3 = 14cm.

Answer 2

Answer:

Let the base side be x cm

Then congruent sides be x+4cm

perimeter of triangle =Sum of all sides

44 cm= (x+x+4+x+4) cm

44 cm=(3x+8)cm

44-8 cm=3x

36 cm=3x

x=12 cm

Thus, base side is 12 cm

and congruent sides=(12+4)cm

=16 cm
