Question

If the perimeter of a square with side 12 cm is equal to the perimeter of rectangle whose length is 16 cm , find its breadth.​

Answer 1

Answer:

The answer is 8 cm

Step-by-step explanation:

Given side length of the square is 12 cm

So its perimeter is $=4\times 12=48$ cm

Given length of rectangle is $16$ cm

Let its breadth be $b$

Thus perimeter of rectangle $=2(l+b)=2(16+b)=32+2b$

Given both perimeters are equal

     $\Rightarrow 32+2b=48\\\Rightarrow 2b=48-32\\\Rightarrow 2b=16\\\Rightarrow b=\frac{16}{2}=8$
