Answer:

You need to take lw (what l equals times what w equals) the area and then take 2l+2l=perimiter

Step-by-step explanation:

Example: 4. area: 12x2=24 the area is 24 units squared. For the perimeter, you need to take 12+12+2+2= 24+4=28 The perimeter is 28 units.

The width of a rectangle is shown below: a coordinate plane with a point a at negative 3, 3 and c at negative 3, negative 4. if

Darya [45]

We have that
a(-3,3) c(-3,-4)

we know that
the distance ab=√[(-4-3)²+(-3+3)²---------> 7 units
[area of rectangle]=length*width
35=L*7--------> L=35/7------> L=5 units

Find point b
point b <span>lie to the right of point a
so
a (-3,3)
b(-3+5,3)-----> b(2,3)

</span>Find point d
point d lie to the right of point c
so
c (-3,-4)
d(-3+5,-4)-----> d(2,-4)

the answer is
b(2,3)
d(2,-4)
