Hii dear,
# Answer- 25 units.
## Explaination-
# Given-
|A| = 7 units
|B| = 24 units
# Solution-
After addition of two vectors, magnitude is given by,
|A+B| = √(|A|^2 + |B|^2 + 2|A||B|cosθ)
|A+B| = √(7^2 + 24^2 + 2×7×24×cos90)
|A+B| = √(49 + 576 + 2×7×24×0)
|A+B| = √(625)
|A+B| = 25 units.
Hope that is useful...
