We can use the equation
to find the length of the side of a square.
<u>Solution:</u>
Given that, the perimeter of a square is equal to the perimeter of an equilateral triangle.
The length of a side of the square is given by "x"
And the length of a side of the equilateral triangle is given by "y"
Finding the equation to determine value of "x"
<em><u>The perimeter of a square with side "x" is given as:</u></em>

<em><u>Perimeter of a equilateral triangle with side "y" is given as:</u></em>

Given that perimeter of a square = perimeter of an equilateral triangle

Hence, we can use the equation
to find the length of the side of a square.
Answer:
11 and 4
Step-by-step explanation:
11 squared plus 4 squared = 137

(I just quickly plugged a few numbers into a calculator that I thought would fit)
Hope this helps :)
Answer:
6m
Step-by-step explanation:
You can use pretend the shape is a whole parallelogram, then divide it, you can only do this when you have a right angle, however. Or you can use a triangle area formula calculator.
4*3 :2
=4*3= 12
= :2
=6m
Two corresponding sides and two corresponding angles are congruent.
