Area = width * height
since the window is 20 inches higher than the width:
width +20 = height
640 = width * width+20
640 = width^2 +20*width
width^2 +20*width - 640 = 0
width = 17.203
**********************************************************
Double Check
if width = 17.203 then height = 37.203
area = 17.203 * 37.203 = 640 square inches Correct!!
you'd use the pythagorean theorem.
a^2+b^2=c^2
a is the first leg, b is the second leg, and c is the third leg.
10^2+13^2=c^2
100+169=c^2
269=c^2
take the square root of both sides
16.4=c
16.4cm is your answer!

hope it helps
Step-by-step explanation:
angle < EDG = 90°
5x + 4x = 90
9x = 90
x = 90/9
x = 10°
which means
5x = 50°
4x = 40°
---------------------------
sice EF and DG are parallel lines
EHD = 40°
DHG is 90°
then HGD = 50°
-----------------------------------------
ED = 64 x2 (2 sides) = 128 inches
DG = 84 x2 (2 sides) = 168 inches
total perimeter = 128 + 168 = 296 inches
and yes. theres enough room for all 3 to cuddle
