A rulerDepending on the degree of accuracy required: a ruler, vernier callipers, micrometer.
length 14cm, width 2cm This is worked out by finding the following equations: perimeter = 16 x width length = width + 12 Then working out 16 x width = 2 x (width + 12) + 2 x width -> 14 x width = 2 x (width + 12) -> 14 x width = 2 x width + 24 -> 12 x width = 24 -> width = 2cm Since lendth = width + 12, length = 14cm
perimeter = length + length + width + width = 2*length + 2*width = 36 length = 5*width 2*(5*width) + 2*width = 36 12*width = 36 width = 3 length = 15
AREA = LENGTH x WIDTH LENGTH = 2 X WIDTH AREA = 2 x WIDTH X WIDTH = 900 900/2 = WIDTH X WIDTH 450 = WIDTH X WIDTH = WIDTH SQUARED WIDTH = SQUARE ROOT (450) = 21.21 FEET LENGTH = 42.42 FEET
= If a rectangle is 10 meters longer than its width what is its width? =
a ruler or a tape measure
The problem is that the width of a line is zero. No drawing instrument can manage that!
A rulerDepending on the degree of accuracy required: a ruler, vernier callipers, micrometer.
A ruler is an example of an instrument that can be used to measure relatively small linear distances, though it could not measure all three at once.
If you have a ruler then you could measure the length width and height and then multiply them together. (LWH is the formula)
A Kaan Lao is a musical instrument. It is made of wood and measures 70 cm in height and 12 cm in width.
L x W x H Lenght x Width x Hieght
That would depend entirely on what other measurements you already have available. If none, then you must use a ruler or other instrument to measure it.
Same instrument as you would use for a line or perimeter (ruler, measuring tape, etc.). However, you multiply width times length for rectangles and more complicated methods for other 2D shapes. If it's a 3D shape, for cubes/rectangular prisms you multiply length times width time height, and more complicated formulas for other shapes.
You measure the linear inches with a ruler or tape measure, then you do the calculation to find out the area (length times width, if it is a rectangular shape).

class width is a width width is a width nothing as class width is a width dont be confuse
