Question

the perimeter of a rectangle is 100 cm and it's largest side is 5cm more than smallest side.find sides?

Answer 1

let the smaller side be x cm
then the larger side = (x+5) cm
Perimeter of rectangle = 100 cm
2×( larger side+ smaller side )=100 cm
2× (x+x+5)=100
2× ( 2x+5)=100
2x+5 =100/2
2x+5=50
2x = 50-5
2x= 45
x= 45/2
x = 22.5
smaller side of rectangle =x cm
= 22.5 cm
larger side of rectangle = (x+5) cm
=(22.5+5) cm
= 27.5 cm
