3. The perimeter of a square is 28 feet. If you increase the length by 2 feet and decrease the width by 1 foot, what is the area of the new figure? A.54 B.40 C.48 D.36

The correct options is;

A. 54

Step-by-step explanation:

The given parameters are;

The perimeter of the square = 28 feet

The increase in the dimension of the length of square = 2 feet

The decrease in the dimension of the width of square = 1 feet

We answer as follows;

Let the length of the side of the square = L

The formula for the perimeter of a square = 4 × L

∴ 4 × L = 28 feet

L =28/4 = 7 feet

L = 7 feet

After applying the given modifications, we have;

The new length, L₁ = L + 2 feet = 7 feet  + 2 feet = 9 feet

The new length, L₁ = 9 feet

The new width, W = L - 1 feet = 7 feet - 1 feet = 6 feet (The width and the length, L of a square are equal)

The new width, W = 6 feet

Therefore;

The area of the new figure = The new length × The new width

Substituting the values gives;

The area of the new figure = 9 feet × 6 feet = 54 feet².

The area of the new figure = 54 feet².

ou would have 12 of each

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
