STEP 1:
find the length of the sides of the square
AREA FORMULA (for a square)
x= side
A=x^2
225=x^2
take square root of both sides
15 feet= x
STEP 2:
find perimeter
PERIMETER FORMULA (for a square)
x= side of square
P= 4x
use x value from step 1
P= 4(15 ft)
P= 60 feet
ANSWER: The perimeter is 60 feet.
Hope this helps! :)
Answer:
50cm
Step-by-step explanation:
oh apdiya I just wanted to let you
The value of x is given by the pythagoras theorem
X^2 = 17^2 - 15^2
X^2 = 289-225
X^2 = 64
X = sqrt64
X= 8cm
