Answer:
x= 4/7
Step-by-step explanation:
Lets assume the sides of the isosceles triangle are:
Side A: x
Side B: x
Base: x/2
x+x+x/2= 46.8cm
2x+x/2=46.8cm
4x+x=93.6
5x=93.6
x= 18.72
Side A: 18.72cm
Side B: 18.72cm
Base: 9.36cm
The base of the largest triangular flag Sara can make is 9.36cm.
2x+x/2= 46.8cm
25 / x = 4 /10
cross multiply
4x = 25 * 10
4x = 250
x = 62.5 or = 62 1/2
D) 62 1/2
