Answer:
the third side is 11 cm and the two equal sides are 30 cm each.
Step-by-step explanation:
let the third side be x cm.
so, the two equal sides are 2x+8 cm each.
now,
x+2x+8+2x+8= 71
5x+16= 71
5x=71-16
5x= 55
x= 55/5
x= 11
x= third side= 11 cm
2x+8= 30 cm
2x+8= 30 cm

Answer:
11cm,30cm and 30cm
STEP BY STEP EXPLANATION →
let the third side be = 'x' cm
let the two equal sides be = (2x+8)cm
given : perimeter = 71cm
therefore, according to the Question →
=>x+2(2x+8) = 71
=>x+4x+16=71
=>5x=55
=>x=11
therefore, the third side is = 11cm
now, each of the two equal sides = 2x+8
=22+8
=30cm ( each of the two )
hope this helped
thanks !!
