320/4(equal sides)= 80. 80 x 80 = 802=6400 square meters.
Area = 30099 square metres pi*radius2 = 30099 r2 = 30099/pi r2 = 9580.809264 r = square root of 9580.809264 r = 97.88160841 Circumference = 2*pi*radius C = 2*pi*97.88160841 C = 615.0082838 metres Therefore the circumference of the circular park is 615 metres corrected to three significant figures.
since this is a square with sides 30 feet use Pythagorean theorem to show hypotenuse is 30 x square root of 2 = 42 feet
An acre is equivalent to 43,560 square feet. Therefore, 0.13 acre is equal to 5,662.8 square feet. In terms of dimensions, this could be visualized as a square plot of land measuring approximately 75.2 feet on each side. This area is commonly used for residential lots or small gardens.
