Question

find area of rectangle whose lenght is 3x+5) breath 2y+4​

Answer 1

Answer:

Area of rectangle=6xy+12x+10y+20

Step-by-step explanation:

Area of rectangle=l×b

Area of rectangle=(3x+5)(2y+4)

Area of rectangle=(6xy)+(12x)+(10y)+(20)

Area of rectangle=6xy+12x+10y+20

Answer 2

Answer:

Area = 6xy + 12x + 10y + 20

Step-by-step explanation:

Length = 3x + 5

Breadth = 2y + 4

Area = l × b

        = 3x + 5 × 2y + 4

        = 3x(2y + 4) + 5(2y + 4)

Area = 6xy + 12x + 10y + 20
