Question

The length of a rectangle is 5 more than the breath.The perimeter of the rectangle is 30cm.therefore its breath=______cm

Answer 1

Answer:5cm

Step-by-step explanation:

Let breadth be x cm

Therefore, length=(x+5)cm

Now,sum of all sides = perimeter

=xcm+xcm+(x+5)cm+(x+5)cm=30cm

4xcm+10cm=30cm

4xcm=20cm

X=5cm

Hence, breadth of rectangle=5cm
