Question 332916
let 2x = side of the square
:
horizontal sides of a rectangle are one half the length of the side of a particular square.
x = horizontal side of the rectangle
:
 The vertical sides of the rectangle are 4 cm more than three times the side of the square.
3(2x) + 4 = (6x+4) vertical side of the rectangle
:
 If the perimeter of the rectangle is twice the perimeter of the square,
 :
rect P = twice square P
2x + 2(6x+4) = 2(4(2x))
2x + 12x + 8 = 16x
8 = 16x - 14x
8 = 2x
x = 4
:
 what are the dimensions of the rectangle?
Rect dimension x by (6x+4); replace x with 4
you have:
4 by 28 is the dimension of the rectangle
:
:
Check by find the perimeter of each
Rect: 2(4) + 2(28) = 64 
square: 4(8) = 32;
