Question

the length of a rectangle is 9m more than it breadth the breadth of rectangle is y metre.area of rectangle is​

Answer 1

Answer:

${ y}^{2} + 9y$

Explanation:

$ar \: ( rectangle) = lb \\ l = y + 9 \\ b = y \\ thus \: ar = y(y + 9) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:= {y}^{2} + 9y$

Answer 2

ANSWER:-

*Given

the breadth of rectangle =y

the length of rectangle=y+9

so,

Area of rectangle=l*b

=y*(y+9)

=y²+9y
