Question

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

• A. $40x^2$$y^3$ square units
• B. $40x^2$$y^2$ square units
• C. $40x{y}^3$ square units
• D. $40xy$ square units

Answer 1

The correct option is A

$40x^2$$y^3$ square units

Given:
Length of the rectangle = $5xy$ units
Breadth of the rectangle = $8x{y}^2$ units

Area of the rectangle
= length $\times$ breadth
$=5xy\times 8x{y}^2$
$=40x^2{y}^3$ square units

Hence, the area of the rectangle is $40x^2{y}^3$ square units.
