let a = side 1 and side 3 of a rectangle
let b = side 2 and side 4 of a rectangle
then the perimeter = a + b + a + b = 2a + 2b+ 28
and the area = a x b = 18
taking 2a + 2b = 28 and making a the subject of the formula you get a = 28-b
taking a= 28-b into the axb = 18 formula gives
b(28-b)=18
so b2-28b+18 = 0
by quadratic formula . i will say b = 14 +/- the root of 178
which you can work out. sorry i have run out of time
b

Why it's not possible to have a perimeter of 20 units with an area of 18 square units?
That would be very difficult to explain, because it's not true. Consider this rectangle: Length = 7.64575 units Width = 2.35425 units Perimeter = 20 units Area = 18 square units =================================== Precise dimensions are: 5 + sqrt(7) 5 - sqrt(7)
What is the number feared by the Pythagoreans?
17. A 4x4 rectangle has a perimeter of 16 units and an area of 16 square units. A 3x6 rectangle has a perimeter of 18 units and an area of 18 square units. The number 17 is halfway between 16 and 18.
What shape has a perimeter of 18 units?
A shape with a perimeter of 18 units can take various forms, such as a square, rectangle, triangle, or any polygon, as long as the total length of all its sides adds up to 18 units. For example, a square with each side measuring 4.5 units would have a perimeter of 18 units (4 sides x 4.5 units). Alternatively, a rectangle measuring 5 units by 4 units would also have a perimeter of 18 units (2 x (5 + 4)). The specific dimensions depend on the type of shape chosen.
What is the perimeter and area of a rectangle that's 4 units and 5 units?
Perimeter: 2(4+5) = 18 units Area: 4*5 = 20 square units
What is the area and perimeter of a rectangle if you have the numbers 18 and 5?
The answer will depend on what those numbers represent and their units. It is possible that the question gives 18 and 5 units as the length and width of a rectangle and requires you to find the area and perimeter. Or It is possible that the question has given 18 in some units and 5 in some other units and requires you to determine which one could be the area and which the perimeter.
How do you find the perimeter of a square with area of 324?
The square root of 324 is 18 and 4*18 = 72 units of measurement which is the perimeter of the square.

What is the area of a rectangle with a perimeter of 18 units on a coordinate plane?
Assuming that the fact that it is a rectangle means that it cannot be a square, then it can have any value in the interval (0, 20.25) square units. This depends on whether the rectangle is a long thin shape or a near-square.
What is the area of a square that has the perimeter of 72?
72 / 4 = 18 per side18 * 18 = 324 units^2
What is the area of a rectangle with a perimeter of 18 units?
Length + width = ½ of perimeter ie 9 units. Area could be anything from 8 square units (8 x 1) to 20 square units (5 x 4), assuming there are no fractional measurements and that rectangle is not a square.
What shape has 15 square units and a perimeter of 18 units?
Make a 3x3 box and a 2x6 box, and join them connecting 2 of the lines.
What are two possible perimeters of an isosceles triangle?
The perimeter of an isosceles triangle can vary based on the lengths of its sides. For example, if the two equal sides each measure 5 units and the base measures 6 units, the perimeter would be 5 + 5 + 6 = 16 units. Alternatively, if the two equal sides are 7 units each and the base is 4 units, the perimeter would be 7 + 7 + 4 = 18 units. Thus, possible perimeters can be 16 units and 18 units.
The perimeter of an equilateral triangle is 18 what is the measure of the altitude?
Given a perimeter of 18 units, the resulting altitude is 5.2 (5.19615) units.
