The area of a square is its side length squared. So the side length of the square squared is 42, so the side length of the square is sqrt(42). The perimeter of the square is 4 times the side length, or 4sqrt(42), which is approximately 25.92.
Answer:
approx 10.25
Step-by-step explanation:
According to Euclid theorem :
EG^2= DG*FG= 16*5=80
From right triangle EDG according to Phitagor's theorem:
DE^2=EG^2+DG^2= 80+25=105
DE=sqrt(105)= approx 10.25
Answer:
27
Step-by-step explanation:
the angle is sitting on a right angle because rhombuses have 4 right angles
90 = 4x-18
108 = 4x
x = 27
