If the rectangle is 12 feet long and has a perimeter of 40, then the height must be 8.
If it is made 6 feet longer, it will have a length of 18 and a height of 8. The new area will be 144.
find the perimeter and area of a rectangle that is 15cm long and 5cm wide
what is the perimeter and area of a rectangle 3cm long and 3cm wide
Without further information it is impossible to say (exactly): If the rectangle was 0.5 x 6.5, its perimeter is 14 units and its area is 3.25 units2 If the rectangle was 1 x 6, its perimeter is 14 units and its area is 6 units2 If the rectangle was 2 x 5, its perimeter is 14 units and its area is 10 units2 If the rectangle was 3 x 4, its perimeter is 14 units and its area is 12 units2 If the rectangle was 3.5 x 3.5, its perimeter is 14 units and its area is 12.25 units2 (and it's a square). It all depends upon the lengths of the longer and shorter sides of the rectangle: as long as 2 x longer + 2 x shorter = 14, any area greater than 0 units2 and less than or equal to 12.25 units2 can be made.
Width of rectangle: 144/18 = 8cm Perimeter of rectangle: 2*(18+8) = 52cm
This question has no unique answer. A (3 x 2) rectangle has a perimeter = 10, its area = 6 A (4 x 1) rectangle also has a perimeter = 10, but its area = 4 A (4.5 x 0.5) rectangle also has a perimeter = 10, but its area = 2.25. The greatest possible area for a rectangle with perimeter=10 occurs if the rectangle is a square, with all sides = 2.5. Then the area = 6.25. You can keep the same perimeter = 10 and make the area anything you want between zero and 6.25, by picking different lengths and widths, just as long as (length+width)=5.
A 9 x 1 rectangle has a perimeter of 20 and an area of 9; A 9.5 x 0.5 rectangle has the same perimeter but an area of 4.75; You can go a long way along this road...
In a rectangle, the longer side is referred to as the "length," while the shorter side is called the "width." These terms help distinguish the dimensions of the rectangle, with length typically representing the side that is longer. When discussing the area or perimeter, these dimensions are essential for calculations.
You cannot find the perimeter unless the rectangle is a regular rectangle (a square) in which case the perimeter is 4 times the square root of the area. With just the area the shape of the rectangle could be any number of shapes with different perimeter, for example, imagine 6 square units 1cm by 1cm arranged in a 1*6 configuration to give a long thin rectangle, the perimeter would be 6+6+1+1=14cm, the same 6 arranged in a 3*2 rectangle would have the same area, but a perimeter of 3+3+2+2=10cm, for this reason a rectangle's perimeter cannot be determined from the area alone.
The rectangle is 6-ft long and 4-ft wide.
Perimeter: 7+3+7+3 = 20 inches Area: 7 times 3 = 21 square inches
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.
The perimeter is 2L + 2W. The area is L x W. As long as you have one of those values, you should be able to solve for the other one.
