Question

The legs of a isosceles triangle are 0.3 foot less then twice the base . The perimeter of the triangle is 4.9 feet .
A: 1.1 feet
B:1.4 feet
C.1.9 feet
D2.2 feet

Answer 1

I hope this helps you

base = b

length= 2b-0.3

Perimeter=b+2b-0.3+2b-0.3

4.9=5b-0.6

5b=5.5

b=1.1

length =2×1.1-0.3

length=2.2-0.3

length=1.9
