Question

What is the area of figure B

Answer 1

The given figure is divided into two rectangles. We will find the area of both reactangles and then add their area to find the total area of the composite figure...

Area of reactangle 1⤵️

• Length = 4cm
• Breadth = 6cm

$\sf \: area = length \times width$

$\sf \: area = 4 \times 6$

$\tt \: area = 24cm ^{2}$

Area of rectangle 2⤵️

• Length = 5cm
• Breadth = 6+4= 10cm

*Note:- The measure of dotted line will be equal to the side opposite to it since it is a rectangle...

$\sf \: area = length \times breadth$

$\sf \: area = 5 \times 10$

$\tt \: area = 50cm ^{2}$

Thus, The area of figure A is 24cm² and area of Figure B is 50cm²....

And the total area of composite figure will be

• 24cm²+50cm²
• 74cm² is the total area...

Answer 2

Answer:

The second option is correct.

Step-by-step explanation:

$Solution,\\Breadth(b)=5cm\\Length (l)=4cm+6cm=10cm\\Now ,\\Area=l*b=5cm*10cm=50cm^{2}$
