The perimeter of a triangle is 93 centimeters. If two sides are equally long and the third side is 9 centimeters longer than the​ others, find the lengths of the three sides. The length of each of the two equally long sides is ▼ square centimeters centimeters and the length of the longer side is ▼ square centimeters. centimeters.

28 & 37 cm

Step-by-step explanation:

Perimeter(P)=9 cm

Let the equal sides(a) be x cm, then third side(b)=(x+9)cm

We have,

P=Sum of all sides

93=a+a+b

or,93=2a+(x+9)

or,93=2x+x+9

or,93-9=3x

or,84/3=x

therefore, x=28

Now,

Length of equal sides=x=28cm

Therefore, The length of each of the two equally long sides is 28 cm

The length of the longer side=(x+9)=28+9=37cm

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
