Answer:
The sides of the rectangle are 3cm and 4 cm
Explanation:
A way we can double check this is using the Pythagorean Theorem.
Your diagonal of 5cm is your hypotenuse.
Your sides of 3cm and 4 cm are also part of this equation.
The Pythagorean Theorem is a^2 + b^2 = c^2
Here's the result:
(3)^2 + (4)^2 = (5)^2
9 + 16 = 25
Since this equation is true, we know that our sides of the rectangle are 3cm and 4cm.
