Question

the perimeter of a square is 64 metre the area of a rectangle is 6 metre square less than the area of the given square if the length of the rectangle is 25 metre find its breadth​

Answer 1

Step-by-step explanation:

Calculate length :

$\implies$ $P=4l$

$\implies$ $64=4l$

$\implies$ $l={\Large\frac{64}{4}}$

$\implies$ $l=16$

Calculate Area of square :

$\implies$ $A=l^{2}$

$\implies$ $A=16×16$

$\implies$ $A=256m^{2}$

Area of rectangle is 6 m² less than area of square = 256 - 6 = 250m²

Calculate breadth of rectangle :

$\implies$ $A=l×b$

$\implies$ $250=25×b$

$\implies$$b={\Large\frac{250}{25}}$

$\implies$ $\boxed{b=10m}$
