Answer:
3/5 when reduced
Step-by-step explanation:
Answer:
-5 multiplied by positive five is your answer
Step-by-step explanation:
Answer:
The answers are:
(i) 108.33%
(ii) 93.75%
Step-by-step explanation:
The original area and perimeter are as follow:
Perimeter = 2l + 2w
= 2(2p) + 2(p)
= 4p + 2p
= 6p cm
Area = l * w
= 2p * p
= 2p^2 cm^2
A 25% increase of the length is = 2p * (1 + 25%) = 2p * 1.25 = 2.5p cm
A 25% decrease of the breadth is = p * (1 - 25%) = p * 0.75 = 0.75p cm
Perimeter = 2l + 2w
= 2(2.5p) + 2(0.75p)
= 5p + 1.5p
= 6.5p cm
Area = l * w
= 2.5p * 0.75p
= 1.875p^2 cm^2
Now that we have found the changes, let's calculate the percentage changes
Percentage change of perimeter:
x% * 6p = 6.5p
x/100 * 6p = 6.5p
x * 6p = 6.5p * 100
x = 650p/6p
x = 108.33
Percentage change of area:
x% * 2p^2 cm^2 = 1.875p^2 cm^2
x/100 * 2p^2 cm^2 = 1.875p^2 cm^2
x * 2p^2 cm^2 = 1.875p^2 cm^2 * 100
x = 187.5p^2 cm^2 / 2p^2 cm^2
x = 93.75
