Answer:
The side length of the square is 3 meters.
The side length of the triangle is 4 meters.
Explanation:
This is basically a systems of equations word problem.
To solve this, we have to create two different equations. Let's assume
is the side length of the square and
is the side length of the triangle.
We can make the equation
, 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
.
Now, let's substitute the second equation (
) into the first (
).
Apply the distributive property:
Subtract 3s from both sides:
So the side length of the square is 3. We can now plug it into the equation
to find the side length of the triangle.
