Given : a rectangle Divided by two lines and a green figure inside
To find : area of Green figure
Solution:
Let say Height of green area = H cm
and Width = W cm
Area of green figure = WH cm²
(8 - W) * H = 25
(9 - W)* H = 32
=> (9 - W) H - (8 - W)H = 32 - 25
=> H ( 9 - W - 8 + W) = 7
=> H = 7
(8 - W) * H = 25
=> 8H - WH = 25
=> WH = 8H - 25
=> WH = 8(7) - 25
=> WH = 56 - 25
=> WH = 31
Area of green figure = 31 cm²
