Answer:
6 feet long and 5 feet wide.
Explanation:
Given that the formula for area is:
A=Length x Width
And perimeter is:
P= 2L + 2W
We know area is 30 and perimeter is 22, so our equations are:
30= L * W
22 = 2L + 2W
To solve as a system of equations, lets isolate L on the second equation.
22 = 2L + 2W
22 - 2W = 2L
Divide both sides by 2
11 - W = L
Inserting it into the first equation
30 = (11 - W) W
30 = 11W - W²
This looks like a quadratic, so let's bring everything to the left side and factor.
W² - 11W + 30 = 0
(W - 6) (W - 5)=0
W= 6 or W= 5
Insert both of these into 30 = L*W to find L
30 = 6L
L= 5 when W = 6
or 30 =5L
L= 6 when W = 5
Hence, the mirror is 6 feet long and 5 feet wide.
Japan changed under the Meiji Restoration because d) It became more old-fashioned. The Meiji Restoration was all about restoring Japanese traditions while advancing the country through modernization. To be able to do these two things which may seem opposed, this was possible through traditional imperial rule with modern ethics and ideas.
