Area = 1/2h(b1 + b2)

60 = 1/2(6)(b1 +12)
60 = 3(b1 +12)
60 = 3b1 + 36
24 = 3b1
24/3 = b1

b1 = 8

The other base is 8 feet

The length of the sides of a triangle are 2x +y/2, 5x/3+y + ½ and 2/3x +2y +5/2. If the triangle is equilateral, find its perime

Sav [38]

Answer:

Step-by-step explanation:

If the triangle is equilateral :

2x +y/2 = 5x/3+y + ½ = 2/3x +2y +5/2

so the perimeter is : P = 3(2x +y/2) or 3(5x/3+y + ½) or 3(2/3x +2y +5/2)

the simplest is : P = 3(2x +y/2)

P = 6x + (3y)/2
