Question

Two gardens are being fenced in. Both gardens will require the same amount of fencing​ (both gardens have the same perimeter in​ meters). One garden is in the shape of a square and the other is in the shape of an equilateral triangle. Each side of the triangle is 1 meters longer than each side of the square.

Answer 1

Answer:

The side length of the square is 3 meters.

The side length of the triangle is 4 meters.

Step-by-step explanation:

This is basically a systems of equations word problem.

To solve this, we have to create two different equations. Let's assume $s$ is the side length of the square and $t$ is the side length of the triangle.

We can make the equation $4s=3t$, since the perimeters are the same. (A square has 4 sides, a triangle has 3 - multiplying by the side length of each will get perimeter)

We also know that the side length of the triangle is 1 meter longer than the side length of the square, so the equation here becomes $t = s+1$.

Now, let's substitute the second equation ($t = s+1$) into the first ($4s=3t$).

$4s = 3(s+1)$

Apply the distributive property:

$4s = 3s+3$

Subtract 3s from both sides:

$s=3$

So the side length of the square is 3. We can now plug it into the equation $t = s + 1$ to find the side length of the triangle.

$t = 3+1\\\\t=4$

Hope this helped!
