Question

Find the area of a rectangle whose breadth is b and length is square of breadth.​

Answer 1

Answer :-

Let the length of the rectangle be "x" and it's breadth be "y"

Now, according to the question,

$y = b \\ x = square \: of \: breadth \: = {b}^{2}$

we know that area of rectangle = Length × Breadth

$area \: of \: rectangle = x \times y \\ = {b}^{2} \times b \\ = {b}^{3}$

Therefore, the area of the rectangle is

${b}^{3} sq.units$

Answer 2

Answer :-

Let us consider the length of the rectangle to be "p" and it's breadth to be "q"

Now,

According to the question,

$q = b \\ p = square \: of \: breadth \: = {b}^{2}$

Now,

Area of rectangle = Length × Breadth

$Area \: of \: rectangle = p \times q \\ = {b}^{2} \times b \\ = {b}^{3}$

Therefore, the area of the rectangle is

${b}^{3} sq.units$
