BC= DF
B(0,2) , C(3,2)
d= (3-0)^2 + (2-2)^2
d= 9
Square root 9= 3
DF = 3
Hope this helps!

Side lengths of the squares are x and y
4x+4y=52
divide both sides by 4 for simlicity
x+y=13
area is 89 so
x²+y²=89
ok
so
x+y=13
minus x both sides
y=13-x
sub that for y in other equation
x²+y²=89
x²+(13-x)²=89
x²+x²-26x+169=89
2x²-26x+169=89
minus 89 both sides
2x²-26x+80=0
undistribute 2
2(x²-13x+40)=0
factor
2(x-8)(x-5)=0
set to zero
x-8=0
x=8
x-5=0
x=5
x=5 or 8
find y
y=13-x
13-8=5
13-5=8
each square has side length of 5 or 8
perimiter is 4 times the area around so
5*4=20
8*4=32
the perimiters are 20cm and 32cm
Answer:
They stopped for lunch at 12:25 pm.
Step-by-step explanation:
They started skyiing at 10:30 am.
They skied for 1 hour and 55 minutes.
1 hour and 55 minutes is 5 minutes less than 2 hours.
2 hours after 10:30 am is 12:30 pm.
Taking the 5 minutes, we have 12:25 pm
They stopped for lunch at 12:25 pm.
