Question

Find the value of x and y from the given rectangle.
8 cm
6 cm
зу cm
(2x - 1) cm​

Answer 1

Answer:

Let the width of rectangle is y cm then length of rectangle is y+8 cm

Then area of total rectangle =y(y+8)=y  

2

+8ycm  

2

 

If a square side x cm cut in this rectangle whose side is half of width of rectangle  

So x=\frac{1}{2}y \Rightarrow y=2x$$

Then area of total rectangle =y(y+8)=y  

2

+8ycm  

2

 put the value y=2x  

Then area of rectangle=2x(2x+8)=4x  

2

+16xcm  

2

 

Then renaming area =4x  

2

+16x−x  

2

=(3x  

2

+16x)cm
