Answer:
10 cm
Step-by-step explanation:
If diagonal of a rectangle is 26 cm and one side is 24 cm, find the other side.
Rectangle has all the angles equal to 90°
and opposite sides are equal
& diagonals are also equal
so pythagoras theorem can be applied here
Diagonal² = One side² + other side²
=> 26² = 24² + other side²
=> other side² = 26² - 24²
a² - b² = (a+b)(a-b)
=>other side² = (26 + 24)(26 - 24)
=>other side² = 50 * 2
=>other side² = 100
=> other side = 10 cm
