First we have to find the width. Let the width be x:
2(12+x) = 30
24+2x = 30
2x = 30-24
2x = 6
x = 3 So the width is 3 units
Area = length*width = 12*3 = 36 square units
Perimeter of a rectangle is 2(l+b).Area of rectangle is 216 centimeter square.
the answer to number 20 is B...12
The shape that has an area of 12 and a perimeter of 16 is a rectangle. To find the dimensions of the rectangle, you can set up equations using the formulas for area and perimeter. Let the length of the rectangle be L and the width be W. The equations would be: 2L + 2W = 16 (perimeter) and LW = 12 (area). Solving these equations simultaneously will give you the dimensions of the rectangle.
Well, honey, if the area is 12 cm² and the perimeter is 14 cm, that means we're dealing with a rectangle. To find the dimensions, you'll need to do some math. Let's break out the algebra and solve for the sides like the math whiz you are.
To find the dimensions of the rectangle, we need to set up equations based on the given area and perimeter. The area of a rectangle is length multiplied by width, so length times width equals 12 cm. The perimeter of a rectangle is given by the formula 2(length + width), which in this case equals 16 cm. By solving these two equations simultaneously, we can find the dimensions of the rectangle.
It is: 12 units in length

the answer to number 20 is B...12
The rectangle would have a width of 2 and a length of 4.

Perimeter = 174cm (75 +75 +12 +12)
Perimeter is the length of a closed line around an area. A rectangle is an area. If each long side of the rectangle is 12 cm and each end of the rectangle is 9 cm, the total length is 14+14+9+9 or 46 cm.
It could be rectangle that has a length of 6 units and a width of 2 units.
