Question

What is the area of this rectangle? (area=length*width)

Answer 1

Step-by-step explanation:

we know that,

• area of rectangle = length × breadth

Now,

rectangle PQRS has it's

breadth = 3

length = 4+b

Then,

area of rectangle PQRS = (4+b) × 3

= 12 + 3b

Hence,

The area of rectangle is 12+3b.
