Hi there!

$\large\boxed{ 9.4m}$

Find the perimeter using the formula:

P = 2l + 2w

It is given that the dimensions are 2.8 × 1.9 so plug these number into the equation:

P = 2(2.8) + 2(1.9)

P = 5.6 + 3.8

P = 9.4m

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?

DedPeter [7]

Answer:

Step-by-step explanation:

Any time you move up or down, it affects the "y" coordinate, and going up is positive so 5 units up is $y + 5$ .

Moving left or right affects the "x" coordinate and moving left is negative so

$x - 3$

$(x - 3, y + 5)$

Hence, C is the correct answer
