Not sure of the answer hope an expert can

Of course for a rectangle A = L × W and we need to be careful about the units.

Here that's

18900 sq cm = L × 180 cm

where the area's in sq cm so we converted the width.  We get

L = 18900 / 180 =  105 cm

We're asked for the result in meters, so that's

1.05 m

The perimeter of the outer rectangle is

18.4 m + 32.5 m + 18.4 m + 32.5 m = 101.8 m

101.8 m

The area of the seating space is the big rectangle minus the small rectangle,

A = 18.4(32.5) - 15(28) = 178 sq m

178 sq m

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

the distance between the school and her home is 3.6km.

12 mins = 0.2 hours = 1/5 hour

54 ÷ 3 = 18km per hour

1/5 of 18 = 3.6km per 12 mins
