Answer:
Step 1 write the equation for perimeter (2L+2W =24)
Step 2 write the equation for area L x W = 32
Step 3 rewrite the equation of area so that one variable is on the right side L=32/W
Step 4 substitute L from step 3 into Equation 1 and simplify 2(32/W)+2W=24
Step 5 having found the width in step 4, use equation 3 to find the length
Step-by-step explanation:
<em>This is just added to show you how to solve but limit your answer to the answer above: rate brainliest please</em>
Area = L*W
Perimeter = 2(L+W)
So say L*W=32 
and 2(L+W) = 24 which is 2L+2W =24
From area L=32/W
Then substitute it into perimeter
2(32/W)+2W=24 if you simplify this you get Width is 4 and 8
then length =32/W but W is 4 and 8 So L= 8 and 4
Meaning you have two options first rectangle is W=4 and L is 8, second triangle W=8 and Length=4

45x = 180
divide by 45
x=4
yes
420 /d = 30
multiply by d
420 =30d
divide by 30
14 =d
no d=14
37+s = 80/2
37+s =40
subtract 37 from each side
s =3
no s=3
52+g =45+11
52+g = 56
subtract 52 from each side
g=4
no g=4
13+14 = 3f
27 = 3f
divide by 3
9=f
yes f=9
