What is the rule for the perimeter of a rectangle?
The perimeter of a rectangle is found by the following formula: (Length x 2) + (Width x 2) or Length + Length + Width + Width.
What is the rule of perimeter?
(length) (times) (width) (times) (two) l x w x 2 = THE TOTAL PERIMETER OF THE SHAPE
What rule can you write for finding the perimeter of a square using multiplication?
s=side length P=perimeter P=4s
How do you find the area of a square with a perimeter?
For a general rule for any object with four sides that have internal angles of 90 degrees just multiply the length by width.
What is the rule for finding the area and perimeter of a parallelogram?
area of parallelogram= base*height perimeter= 2(length+breadth)
What is the rule for finding the area of a rectangle?
Length times width.
What is the rule for working out the area of a rectangle?

What is a rule for the area of a square?
length x width= area ex if the length of the square was 10 and the width was 5, 10 x 5= 50units^2

What is the length and width of a rectangle with the perimeter of 60 and an area of 224?
The length of the rectangular slab = LThe width of the rectangular slab = WThe formula for perimeter in terms of the length and width is 2L + 2W = 60The area =L*W = 224So L=224/WWe substitute that into the formula for perimeter and we haveP=2(224/w)+2w=60This can be simplified tow2-30w+224=0 so we can solve it and find w.Fortunately, it factors or else we would need to use the quadratic equation.(w-14)(w-16)=0. Now we use the zero product rule and we findthe solutions are 14 and 16. This means the rectangle is 14x16. We need to check the answer.We note that 14x16=224 so that is the desired area and 14x2+16x2=28+32=60 which is the desired perimeter.
