Question

the length of rectangle is 16 cm if its perimeter is 50 cm find its breadth

Answer 1

length of rectangle=16cm
perimeter=50cm
2(l+b)=50
16+b=25
b=9cm
So, breadth=9cm

Answer 2

length of rectangle=16
breadth of rectangle=x
perimeter of rectangle=2(l+b)
2(16+x)=50
32+2x=50
2x=50-32
2x=18
x=9
breadth=9
