A garden has a perimeter of 21cm . if the garden is in the shape of an equilateral trianglewhat are the lenghts of the sides?

Lengths of the sides = 7 cm.

Step-by-step explanation:

An equilateral triangle is a triangle in which all three sides are equal.

If the side length of the equilateral triangle = x

The perimeter of the equilateral triangle = 3x

Given:

A garden is in the shape of an equilateral triangle and its perimeter = 21 cm

So, each side length of the garden = 21/3 = 7 cm.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
