I'm having some trouble understanding exactly what 'm' and 'x' have to do with the rectangle. A look at the drawing would really help.
Let the width be x-12 and the length be x: 2(x-12+x) = 52 2x-24+2x = 52 2x+2x = 52+24 4x = 76 Divide both sides by 4 to determine the value of x: x = 19 Therefore: width = 7 cm and the length = 19 cm
52. The absolute value is the nonnegative value of a number. Enclosing vertical bars ( | | ) are the absolute value operator. Using that notation we can state that |a| = a, and |-a| = a. You can also note that |a| (whether a is negative or positive) equals the square root of a squared.
7 x 19 cm
Perimeter of a rectangle = 2 x length + 2 x width. 52 = 2l + 2 x 12 = 2l + 24 (Where l is the length) 2l = 52 - 24 = 28 length = 28/2 = 14 cm

The equation for the perimeter of a rectangle is 2x(a+b) where a is the length and b is the width. We can rewrite the question as the following: 2x(52+b) = 182 If both sides are divided by 2 we get: 52+b = 91 If we subtract 52 from both sides we get: 91 - 52 = 39. Thus the width of the rectangle is 39 in.
Let the width be x-12 and the length be x: 2(x-12+x) = 52 2x-24+2x = 52 2x+2x = 52+24 4x = 76 Divide both sides by 4 to determine the value of x: x = 19 Therefore: width = 7 cm and the length = 19 cm
What is the value of the 2 in 52
52 ft
2*24
If the rectangle is a square, the perimeter is 48 cm. If not, there are a lot of possibilities.

Strangely enough, it is 52.
