Question

If diagonal of a rectangle is 26 cm and one side is 24 cm, find the other side.

Answer 1

Define x:

Let the length of the other side be x

Solve x:

a² + b² = c²

24² + b² = 26²

b² = 26² - 24²

b² = 100

b = √100

b = 10 cm

Answer: The length of the other side is 10 cm

Answer 2

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
