20 / 2 = 10So 10 lengths can be cut from 20 metres.ten20 / 2 = 10
Let the lengths be 2x and 5x If: 2*(2x+5x) = 224 then x = 16 So therefore the lengths are 32 and 80 because 32+80+32+80 = 224

A rectangle has 2 pairs of parallel lines of different lengths but a square has 2 pairs of parallel lines of equal lengths
A lap is technically 2 lengths. And every 2 lengths in 50 yards. Therefore, you would have to swim 10 lengths (or 5 laps) to complete 250 yards.
16 lengths (down and back counts as 2 lengths)
A cube cannot have different side lengths.
The ratio of areas is the square of the ratio of lengths. Ratio lengths = 1 : 2 → ratio areas = 1² : 2² = 1 : 4 → if the lengths are doubled, the areas of quadrupled (multiplied by 4).
When they have the same chord lengths
