5cm because the square root of 121 is 11 and 5 plus 6 equals 11.
(X+4)2=256 X+4=16 X=8 the sides of the original square is 8 cm
The new square has an area of 121, so the length of a side is the square root of 121, or 11. So the length of the side of the old square was 10.
length 80 mtr and width 40 mtr
11cmThe area of the square is 121cm2. Since the area of a square is just one side squared, to find the length of one side take the square root of the area. In this case the square root of 121 is 11. So the answer is 11 cm.
Use the formula Strain=Extension/original length and rearrange to give Original length=Extension/Strain. Substitute the values you have for the strain and the extended length into the equation and voila! Source: Doing A-level (senior high-school in America) Maths and Physics.
256 divise by 4
(X+4)2=256 X+4=16 X=8 the sides of the original square is 8 cm
256 = 162; 16 - 7 = 9 cm
New area = 256 so new side = sqrt 256 = 16 so old side = 12 (so old area = 144)
The new square has an area of 121, so the length of a side is the square root of 121, or 11. So the length of the side of the old square was 10.
The verb of length is lengthen.Other verbs are lengthens, lengthening and lengthened, depending on the tense.Some example sentences are:"We will lengthen your contract"."This lengthens everything"."They are lengthening the pole"."It has been lengthened".
IF you mean it has been extended by 2.9m from 7.8m - the new length is 10.7m. IF you mean its extended length is now 7.8m after adding 2.9m - its original length was 4.9m

Yes this is true. If a length is doubled (d becomes 2d) then the original area (d2) becomes (2d)2 = 4d2. The area is therefore four times as large.
b/c we know that change in length is directly preposterously to original length and change in temperature. SAIFULLAH JAMALI INSTITUTE OF PHYSICS UNIVERSITY OF SINDH
