a square area will be 8x8=64. Formula is a2 + b2 = c2. In other words the square root of (8x8 + 8x8) 128 which is 11.31371
Area = 64 cm2 so length of side = 8cm Then, by Pythagoras, length of diagonal = sqrt[82 + 82] = 8*sqrt(2) = 11.3137 cm (to 4 dp)
About 5.656854249 cm using Pythagoras' theorem: 2x2 = 64
8 feet length x width = area, or in a square, length x length = area 8 x 8 = 64

64 sq. units
The square's diagonal is 11.314 cm
Area = 64 cm2 so length of side = 8cm Then, by Pythagoras, length of diagonal = sqrt[82 + 82] = 8*sqrt(2) = 11.3137 cm (to 4 dp)
The length of each side of a square with an area of 64 is: 8.

Firstly you need to work out the length of a side. Using Pythagorean Theorem for a right angled triangle a2+b2=c2 where a = the length, b = height & c = diagonal since c = 8 and a = b are the same 2a2 = 64 a2 = 32 a = 5.657 cm since the area of the square is a2 then area = 32cm2
8 feet length x width = area, or in a square, length x length = area 8 x 8 = 64
64
The length is 8mmyou find the square root of 64mm and your answer will be 8mmJust a clarification in terms of notation and units...64mm is a measure of length, not area. The proper designation is 64 mm2 or 64 square mm.
64 square inches
Since a square has four sides that are all of equal length each side is of length 32/4, or 8. The area of the square garden is length times width, 8 x 8, or 64. 64 square feet? 64 square meters? 64 square inches? Your question didn't specify any units.
A square with a side length of 8 units has an area of 64 square units.
