Let X represent the length, then X-4 represents the width. Perimeter of the rectangle is length plus width multiplied by two. Hence, 2(X + X - 4) = 100; 4X - 8 = 100; 4X = 108; X = 27. The length is 27 mm and the width is 27 - 4 = 23 mm. width = w
length = w + 4
perimeter = w + w + w + 4 + w + 4 = 100
4w + 8 = 100
4w = 92
w = 23
width = 23
length = 27
area = 23 x 27 = 621

What is a perimeter of a square whose area is 625cm square?
The perimeter is 100cm
What is the area of a square whose side is 100cm in lenght?
Area = length x width Area = 100cm x 100cm Area = 10000cm2
How many cm2 are in one m2?
One square meter has a length of 100 centimeters and a width of 100 centimeters, so its area measured in centimeters would be: 100cm * 100cm, which equals 10,000cm^2
How many meters squared in 100cm squared?
100cm squared = 0.01 metres squared
What is 0.8m in cm?
80cm (100cm per meter).
The length of a rectangle is fixed at 24 cm what widths will mame the perimeter greater than 100cm?
P (perimeter of a rectangle) = 2*l+2*w 2*24+2*w > 100 2*w > 52 w > 26 Any width greater than 26cm will cause the perimeter to be greater than 100cm.
What would the side length be for a square with a perimeter of 100cm?
25 cm
The perimeter of a regtangle is one meter each longer side is 34cm what is the lenght of each sorter side?
The length of the shorter side is 16cm The formula for the perimeter of a rectangle is p = 2a + 2b, p = 100cm, a = 34cm 2b = p - 2a = 100 - 68 = 32 b = 16cm
How many centimeters would be in a car that measures 5.25 meters in length?
100cm in a meter, so 525cm.
What is the perimeter of 24cm by 100cm?
248cm. Why? Because it is a rectangle so the perimeter is length + length + width + width or just widthx2 + lengthx2. So, 24x2=48 and 100x2=200. 200+48=248cm.
What is a perimeter of a square whose area is 625cm square?
The perimeter is 100cm
What is the total length of the 100cm triangle in millimetres?
There are 10mm in a centimetre. Therefore to convert the perimeter, you multiply by 10. This gives you 1000 (i.e.100x10)mm
The length of a rectangle is 100cm what is the width of the rectangle if the perimeter is 6 times the width?
P = 2(100 + W) and P = 6W so 200 + 2W = 6W making 4W = 200 so W = 50 cm.This suggests that in any rectangle with a length twice the width, the perimeter is 6 times the width. eg 56 x 28: 56 + 28 = 84 x 2 = 168 = 6 x 28.Simple proof: P = 2 (L + W) but L = 2W so P = 2 (2W + W) = 2 x 3W = 6W. QED
What is the side of a square whose perimeter is 100cm?
25=side
What is the area of a square whose side is 100cm in length?
The area of a square is the length of a side squared (multiplied by itself)A square that have 100 cm on all sides is 100cm*100cm = 10,000 cm2
What is the area of a square whose side is 100cm in lenght?
Area = length x width Area = 100cm x 100cm Area = 10000cm2
