Question

The perimeter of a square is 48 m the area of a rectangle is 4 sq m less than the area of the given square if the lenght of the rectangle is 14 cm then find its breadht

Answer 1

hope it helps !!!!!!!!

Answer 2

Answer:

$Breadth \: of \: rectangle (b)= 1000\:m$

Step-by-step explanation:

i ) Let side of a square = a m

Perimeter (P)=48 m (given)

=> 4a = 48

/* Divide both sides by 4, we get

=> a = 12 m

and

Dimensions of a rectangle:

length (l) = 14 cm = 0.14 m

Let breadth = b m

According to the problem given,

The area of a rectangle is 4 sq m less than the area of the given square

=> lb = a²-4

=> 0.14b = (12)²-4

=> 0.14b = 144-4

=> 0.14b = 140

$\implies \frac{14b }{100}= 140$

$\implies b = \frac{140\times 100}{14}\\=1000 \: m$

Therefore,

$Breadth \: of \: rectangle (b)= 1000\:m$
