Question

Base of isosceles triangle is 1/4 the length of one of its legs. The perimeter of triangle is 16, what is the length of the base.

Answer 1

Answer: 7.88 or 7 7/8

Step-by-step explanation:

Perimeter= sum of two equal sides + third side

; P= 2a + b

a = P/2 -b/2

a = 16/2 - 1/4/2

a = 16/2-2/4

a = 63/8

a= 7.88 or 7 7/8
