Question

find the area and perimeter of an rectangle with the following length and breadth respectively 4 x square y,3bxy square

Answer 1

Hey there
Length = 4x²y
Breadth = 3bxy²

Perimeter = 2( 4x²y + 3bxy²) = 2 xy ( 4x + 3by) = 8x²y + 6bxy²

Area = 4x²y ( 3bxy²) = 12b x³y³

Hope helped!

Answer 2

Lenght :- 4x²y
Breadth :- 3bxy²

Now,

Perimeter of rectangle =2(lenght + breadth)
Perimeter of rectangle =2(4x²y+3bxy²)

Perimeter of rectangle =2xy(4x+3by)
Or

Perimeter of rectangle =8x²y +6bxy²

___________

Area of rectangle = lenght * breadth

Area of rectangle =4x²y*(3bxy²)

Area of rectangle =12x³y³b


I hope this will help you
