you can find the length of the side of a square by square rooting the area, which is 225. the square root of 225 is 15
5 since both numbers are divisible by 5 and not by any smaller number
..................................
Steps:
Shape: Regular octagon
Solved for area
Side= 10cm
Formula: A=2(1√+2)a2
Round to the nearest tenth = 482.8
Description:
Using the formula for the area of Regular octagon ( A=2(1√+2)a2) We have to calculate the side length that is 10 cm. Your answer will equal as A≈482.84cm² after you calculate. Since it says to round to the nearest tenth your answer will come as 482.8.
Answer: A≈482.84cm²
