An equilateral triangle and a square have the same perimeter. one side of the triangle measures 28 units. what is the area of the square

The perimeter of a triangle assuming that all the sides are the same, would be 3 multiplied by 28 to get 84. Since the perimeter of the square is the same, that would mean that 84 units is the total addition of the 4 sides of the square. So divide 84 by 4 to get the length of one side ( which is 21 units).  

Finally, the area of a square is defined as two sides multiplied by each other, so 21 multiplied by 21.

**just correcting the previous users math mistake when he divided 84/4 = 21 not 24!

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

24
