Question

A rectangle have perimeter of 24cm and length is 9cm.Finds its breadth and area​

Answer 1

The perimeter of a rectangle is given by the formula:
length+length+breadth+breadth= perimeter

So, you have to substitute the values in using the question ( breadth plus breadth becomes 2b)


9+9+2b=24


18+2b=24


Take 18 to the other side as a negative number


2b= 6


Divide both sides by 2


Therefore, the breadth is 3cm




The area of rectangle is given by the formula:


length*width=area


Using the breadth, the area is 9*3, which is 27cm^2
