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
If the base of a triangle is doubled while the other sides remain unchanged, the perimeter of the triangle will increase by the amount equal to the original base length. Specifically, if the original base is ( b ) and the other two sides are ( a ) and ( c ), the new perimeter becomes ( (2b + a + c) ), resulting in an increase of ( b ). Thus, the total perimeter becomes the original perimeter plus the original base length.
When the breadth of a rectangle is doubled, the area of the rectangle also doubles. The area of a rectangle is calculated by multiplying its length by its breadth (Area = Length × Breadth). Therefore, if the original breadth is increased to twice its size, the new area becomes Area = Length × (2 × Breadth), resulting in double the original area.
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.
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
length 80 mtr and width 40 mtr
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".
When the length of a tube is shortened, the resonant frequency increases. This is because shorter tubes have shorter wavelengths, leading to higher frequencies. Conversely, if the length of the tube is lengthened, the resonant frequency decreases.
The verb of length is lengthen.Others, depending on the tense, are lengthens, lengthening and lengthened.Some example sentences are:"We will lengthen the road"."She lengthens her hair"."We are lengthening the deadline"."The ghostly arm lengthened towards the grave".
When the breadth of a rectangle is doubled, the area of the rectangle also doubles. The area of a rectangle is calculated by multiplying its length by its breadth (Area = Length × Breadth). Therefore, if the original breadth is increased to twice its size, the new area becomes Area = Length × (2 × Breadth), resulting in double the original area.
The formula for extension (lengthening) of a material under tensile stress is given by: Extension = Original Length x Strain = Original Length x (Final Length - Original Length) / Original Length. It represents the change in length of a material when subjected to a stretching force.
