Asquare has a length of 4.8 feet. if the square is dilated by a factor of 4 , what is the length of a side of the new square? what is the new shape's perimeter and area

the length of a side of the new square is 19.2 feet and it's perimeter is 76.8 feet and area is 368.64 feet².

Step-by-step explanation:

Given:

A square has a length of 4.8 feet. If the square is dilated by a factor of 4.

Now, to find the length of a side of the new square and the new shape's perimeter and area.

So, as given dilated by a factor 4 that means it is enlarged so we multiply the length with the dilated factor to get the length of a side of the new square.

Length of a side of the new square = 4.8 feet × 4 = 19.2 feet.

Now, to get the perimeter and area of the new shape we put the formula:

Perimeter = 4 × length

Area = (length)²

Therefore, the length of a side of the new square is 19.2 feet and it's perimeter is 76.8 feet and area is 368.64 feet².

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

7/2
