Question

What is the area of the rectangle having a length of (2a + b) cm and breadth of b cm?

• A. $(2ab+b)c{m}^2$
• B. $(2a{b}^2+b)c{m}^2$
• C. $(2a^{2}b+b)c{m}^2$
• D. $(2ab+b^2)c{m}^2$

Answer 1

The correct option is D $(2ab+b^2)c{m}^2$

Given,
Length of the rectangle $=2a+b$ cm
Breadth of the rectangle $=b$ cm

Area of the rectangle
$=length\times breadth$
$=(2a+b)\times b$
$=(2ab+b^2)c{m}^2$
