The answer to this question is 48.
No, because square root of 26 is 5.099
otal perimeter = 76cm = AB + BC + CD + AD
AD & BC = 13cm
AB = 1.5*(CD)
Solution:
Since we know AD & BC are both 13cm long, plug those numbers into the perimeter equation
76cm+=+AB+%2B+BC+%2B+CD+%2B+AD Place 13cm in for AD & BC
76cm+=+AB+%2B+13cm+%2B+CD+%2B+13cm Combine like terms
76cm+=+AB+%2B+CD+%2B+26cmSubtract 26cm from both sides
50cm+=+AB+%2B+CD Now it is time to substitute the 1.5*(CD) for AB
50cm+=+1.5%2A%28CD%29+%2B+CD rewrite the equation
50cm+=+2.5%2A%28CD%29 Divide both sides by 2.5
20cm+=+CD
To find AB, plug 20cm in for CD in the equation AB = 1.5*(CD)
AB+=+1.5%2A20cm
AB+=+30cm

Step-by-step explanation:
(x,−1) and (4x−2,5) is 10
![\sqrt{(4x - 2 - x)^2 + (-1 - 5)^2} = 10](https://tex.z-dn.net/?f=%20%5Csqrt%7B%284x%20-%202%20-%20x%29%5E2%20%2B%20%28-1%20-%205%29%5E2%7D%20%3D%2010%20)
