Is 18 cm 280 mm?
No because 280 mm equals 28 cm
What are the dimensions of a rectangle which has an area of 72cm2 and perimeter of 44 cm?
Suppose the Length and Width are L and W. Then Perimeter: 2(L + W) = 44 so that L + W = 22 and W = 22 - L and Area: L*W = 72 so that L*(22 - L) = 72 ie L2 - 22L + 72 = 0 (L - 4) (L - 18) = 0 Then L = 4 giving W = 18 or L = 18 giving W = 4 Since L > W (by convension), the answer is L =18 cm and W = 4 cm Substituting the
A rectangle has a width of 6 cm and a perimeter of 30 cm what is the length of the rectangle?
30=2(6)+2(l) 30=12+2(l) 18+2(l) length is 9 cm
What Is the perimeter if a rectangle if the area is 45cm2?
Any number greater than or equal to 4*sqrt(45) cm or 26.83 cm (approx). To see that, suppose L ≥ sqrt(45) cm be the length of the rectangle and let B = 45/L cm Then Area = L*B = L*(45/L) = 45 cm2 If L = 9cm, then B = 45/9 = 5 cm and then perimeter = 2*(L+B) = 28 cm If L = 90 cm, then B = 0.5 cm and P = 181 cm If L = 900 cm, then B = 0.05 cm and P = 1800.1 cm If L = 9000000 cm then B = 0.000005 cm and P = 18000000.00001 cm As can be seen, the perimeter can be increased without limit.
The perimeter of a rectangle is 90 cm. If the length is one and one-half times the width Find the length and the width?
Suppose the length is L cm. Then the width, W, is 2L/3 cm. Perimeter = 2(L+W) = 2(L+2L/3) = 10L/3 = 90 cm So L = 27 cm and W = 2L/3 = 18 cm.
A rectangle has a perimeter of 52 cm and a width of 12 cm What is the length?
P=2(w)+2(l) 52=2(12)+2(l) 52=24+2l 52-24=2l 28=2l 14=l The length is 14 cm.
How many inch in 28cm x 18 cm?
This question cannot be answered sensibly. The given measure, 28 cm x 18 cm is a measure of area, with dimensions [L2]. An inch is a measure of distance, with dimensions [L]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
What is the length and width of a rectangle if the perimeter is 18cm?
It is impossible to say. Let L be ANY number such that 4.5 ≤ L < 9 cm and let B = (9 - L) cm. Then for every one of the infinite number of values of L, there will be a different rectangle whose perimeter will be 18 cm.

The length L of a rectangle is 3 times its width The perimeter of the rectangle is greater than 48 centimeters Which inequality expresses all the possible lengths in centimeters of the rectangle?
Number of miles in the car can travel varies directly with the amount of gas in its fuel tank if K is the concert which equation represents that situation
How write 28 cm in meters?
100 cm = 1 metre so 28 cm = 28/100 = 0.28 metres. So simple!100 cm = 1 metre so 28 cm = 28/100 = 0.28 metres. So simple!100 cm = 1 metre so 28 cm = 28/100 = 0.28 metres. So simple!100 cm = 1 metre so 28 cm = 28/100 = 0.28 metres. So simple!
