You got AB right. It is 24.
in DBC, BC is 24, hence the sum of other two sides is 50-24=26.
Sincs DBC is isosceles the other two sides are 13 and 13.
Hence the answer is 24+13=37

Could you take a look at the attachment and let me know what to do?
Also would this be correct?
[FONT='Arial','sans-serif']NDBA is a rectangle with parallelogram GDFA enclosed. If[/FONT][FONT='Arial','sans-serif'] AN = NG, BF = DB, GD = 11, and DF = 8√2. What is the area of GDFA?[/FONT]
Area = height *base
Base=GD=AF=11
DBF is an isosceles right triangle so DB=FB. To get DF take x2+x2=([FONT='Arial','sans-serif']8√2)2=2x2=128 so x=8[/FONT]
[FONT='Arial','sans-serif']Would this make the area 88?[/FONT]
Can I try #1? Triangle ABC is an equalateral so each side is 24. Triangle DBC is an isosceles with base BC which is 24. The perimeter of Triangle DBC is 50
We have 2 unknown sides + the base which equals the perimeter
So 2*a + 24 = 50 What we should get is a = 13
So AB + BD = 37 because 24 + 13 = 37
Hello, Sanee!
They gave us: .C. In the trapezoid KLMN, OP joins the midpoints of two sides, and
If , which is the perimeter of the trapezoid?
. .Code:K L • * • * * * * * * O• * * * * * •P * * * * * * • * * * * * * * * * • N M
. . We have the total length of the two parallel sides.
They gave us: .
Since and are midpoints: .
Hence: .
. . And we have the total length of the two nonparallel sides.
Therefore, the perimeter is: .
[FONT='Times New Roman','serif']Area of the of square P is 36 square inches and the perimeter of the rectangle R is 144 inches. If a width of the rectangle is two times a length of the square, which is the length of a length of the rectangle?
[FONT='Times New Roman','serif']70,60,45,30[/FONT]

[FONT='Times New Roman','serif']If the area is 36 then each side is 9 square inches. the perimeter is 144 with a width of 2*9.[/FONT]
[FONT='Times New Roman','serif']Then 144=2(18+b) gets to be b=54 Where am I wrong at?[/FONT]
Hello, Sanee!
Area of the of square is 36 in²
and the perimeter of the rectangle is 144 inches.
If a width of the rectangle is two times a length of the square,
which is the length of a length of the rectangle?
. .
If the area is 36, then each side is 9 inches. . ← Here!
The area is 36 in², so the side is six inches.
