Part B: Plot point C(2,7). If M is the midpoint of CD, what are the coordinates of D?

Step-by-step explanation:

Given

Required

The coordinates of D

Represent D with:

Using midpoint formula, we have:

So, we have:

Multiply both sides by 2

Compare both sides

In , we have:

In , we have:

So, the coordinates of D is:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

b.-4 units

all you   do is count how many times you move
