Question

find the area of green figure ​

Answer 1

Answer:

Step-by-step explanation:

(8- y ) A = 25 ......(1)

(9-y) A = 32 ....(1)

9A - yA - 8A -y A= 32 -25

1 A = 7

A = 7

(x +y) A = 25 + required area

8 * 7 = 25 + required area

31 = Required area

So the area of green Shaded part is 31 cm²

Answer 2

Given :

A figure containing problem .

To find :

The area of the green region .

Solution :

The breadth is the same for all regions .

Let the breadth be y and the length of the green region be x .

Now ,

( 9 - x ) * y = 32 $cm^{2}$                ....(i)

( 8 - x ) * y = 25 $cm^{2}$                ....(ii)

subtracting (ii) from (i) ,

( 9 - x ) * y - ( 8 - x ) * y = ( 32 - 25 ) $cm^{2}$

=> 9y - xy - 8y + xy = 7 $cm^{2}$

=> y = 7 cm

putting the value of y in (i) ,

( 9 - x ) * 7 = 32 $cm^{2}$  

=> 63 - x*7 = 32 $cm^{2}$  

=> area of the green region = x*7 =  ( 63 - 32 ) $cm^{2}$

=>  area of the green region = 31 $cm^{2}$

The area of the green region is 31 $cm^{2}$ .
