Answer:
The length is 15 cm and the width is 10 cm
Step-by-step explanation:
You can solve this using basic algebra.
2(x) + 2(y) = 50
We know that x = y + 5
So if we did 50 - 5 -5 = 40, we would have to split that into 4 groups (10 + 10 + 10 + 10) and give 2 of those groups +5.
So we would get 10 + 10 + 15 + 15
10 + 10 + 15 + 15 = 50
