Find the area of a rectangle whose length is 5 x y units and breadth is 8 x y 2 units. Options: A . &nbsp 40 x 2 y 3 square units B . &nbsp 40 x 2 y 2 square units C . &nbsp 40 x y 3 square units D . &nbsp 40 x y square units

Answer: Option A : A Given: Length of the rectangle = 5 x y units Breadth of the rectangle = 8 x y 2 units Area of the rectangle = length × breadth = 5 x y × 8 x y 2 = 40 x 2 y 3 square units Hence, the area of the rectangle is 40 x 2 y 3 square units.

Find the area of a rectangle whose length is 5xy units and breadth is 8xy2 uni

Question

Find the area of a rectangle whose length is $5 x y$ units and breadth is $8 x y^{2}$ units.

Options:

A .

40 x^{2}

y^{3}

square units

B .

40 x^{2}

y^{2}

square units

C .

40 x y^{3}

square units

D .

40 x y

square units

Answer: Option A
:
A

Given:
Length of the rectangle = $5 x y$ units
Breadth of the rectangle = $8 x y^{2}$ units
Area of the rectangle = length $\times$ breadth
$= 5 x y \times 8 x y^{2}$
$= 40 x^{2} y^{3}$ square units
Hence, the area of the rectangle is $40 x^{2} y^{3}$ square units.
