Question

If the side of any square is decreased by 50% then what % |
change in its area will occur?​

Answer 1

Answer:

75%

Step-by-step explanation:

let original side = 10 cm

original area of square=(10)^2=100cm^2

new side = 10 - 50% of 10 = 5 cm

new area = (5)^2 = 25 cm^2

decrease in area = 100-25 = 75 cm^2

% change= 75/100 * 100 = 75%

2nd M,

% change = 50 + 50 - (50×50)/100=75%

Answer 2

Answer:

75% will change its area will occur 25% will more take to change area of the square because if it decreases by 50% then if we add 25% will get 75% 75% is the answer
