Question

A rectangle has perimeter 14 cm. Find the breadth of the rectangle if the length is 4cm​

Answer 1

perimeter of rectangle = 2 (l+b)

14 = 2 (l+b)

l+b = 7

4+b = 7

b = 3

therefore the breath of the rectangle = 3 cm

Answer 2

perimeter of rectangle =2(l+b)

14=2(4+b)

14/2=4+b

7-4=b

therefore b=3 ,that is breadth
