(w = width)
10 x w = 40
(divide both sides by 10)
1 x w = 4
w = 4
80 meters
Perimeter= 2length x 2widthSince the perimeter is 40 and 2 times the width is 16, that means 2 times the length is 24. The length is 12.
It is: 70cm+1m 40cm = 2m 10cm
40 cm (10cm x 4 sides = 40cm)
26cm
The width will be 30cm
80 meters
Perimeter= 2length x 2widthSince the perimeter is 40 and 2 times the width is 16, that means 2 times the length is 24. The length is 12.
The hollow block sizes in the Philippines are the following:40cm (length) X 20 cm (width) X 4 in (thickness)40cm (length) X 20 cm (width) X 5 in (thickness)40cm (length) X 20 cm (width) X 6 in (thickness
It is: 70cm+1m 40cm = 2m 10cm
First, you must find the width. Use Pythagoras' Theorem. Then, just add the lengths of the four sides, to get the perimeter.

20 x 40 x 10 = 8,000 cm3 = 8 liters
The rectangle is 99 cm2 in area. Here's how we got it. The rectangle has length (l) and width (w). A length and a length and a width and a width all added up equals 40 cm. And l is 2 cm longer than w, so l = w + 2. If we add w + 2 and w + 2 (the two lengths) and w and w, we get 40 cm. That's 4w + 4 cm = 40 cm. 4w = 36 cm, and w = 9 cm. The width is 9 cm, and the length is 2 cm more or 11 cm. The rectangle is 9 cm by 11 cm, and its area is 9 x 11 cm2, or 99 cm2.
40cm (4 x 10 = 40)
If one side is 10cm...10 x 4 = 40cm
Perimeter = 40cm. Area = 100cm2
