A rectangle and an equilateral triangle have the same perimeter.
The perimeter of the rectangle is
2x + 2(3x – 1) inches.
The perimeter of the equilateral triangle is
3(x + 1) inches.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
