The perimeter of the equilateral triangle is 3s and s=4x so the perimeter is:
12x
And we are told that the perimeter of the square is the same. And that perimeter is 4s where s=(x+6) so that perimeter is equal to
4x+24, and again, we are told that these two values are equal so we can solve for x...
12x=4x+24
8x=24
x=3 and if x=3 then the side length is (x+6)=9
So the area of the square is always A=s^2 and s=9 thus:
A=9^2
A=81 u^2
Answer:
- 1.9f - 18
Step-by-step explanation:

Answer:. If the Area is 177, it should have been given in square centimeters.
If one side is 13 cm, the other side is about 13.6cm.
If one side is 11 cm, the other side should be about 16.1 cm. Even the choice is incorrect!
A/x = w
Step-by-step explanation: to find a side when the Area is given, divide the Area by the length or width given.
4y.
Is the answer
Hope this helps
