Question

find the length of a rectangle with perimeter 32cm and breadth 4cm​

Answer 1

Answer:

Step-by-step explanation:

perimeter of a rectangle =  32 cm

breadth = 4cm =b

let length be l

2(l+b) = 32

l+b = 16

l+4 =16

l=12 cm

Answer 2

Answer:

perimeter of the rectangle=32cm

breadth=4 cm

perimeter of rectangle=2(l+b)

32=2(4+b)

32÷2=(4+b)

16-4=b

b=12

so we can say that breadth of the rectangle is 12cm
