Answer 1

we know isosceles triangle have two sides equal with an unequal base

perimeter is 41cm

length of equal sides= 5cm

let base length be x

now perimeter of triangle

=> x+5+5=41

=> x= 41-10

=> x= 31

Answer 2

Step-by-step explanation:

perimeter of isosceles triangle are= 2a+b

so 2(5+b)=41

10+b=41

10-41=b
