Question

if lenght of a rectangle is(3+y)and breath is (4+y) then find it's area​

Answer 1

Answer:

$\sqrt{?}$

Given that,

Length (l)=4x

2

−3y

Breadth (b)=5xy

Area of rectangle =l×b

=(4x

2

−3y)×5xy

=20x

3

y−15xy

2

sq.units

Answer 2

Answer:

Step-by-step explanation:

length=3+y

breadth=4+y

Now we have to  find area.

area of rectangle = l*b

area= (3+y)(4+y)

=3(4+y) + y(4+y)

=12 + 3y +4y + y^2

y^2 +  7y + 12
