Question

a lot measures 10 m by 26 m on its bases and 8m height. at the center of the lot is a house with floor dimensions of 12 by 10.5m. Find the area not covered by the house.

Answer 1

What part are you having trouble with? You just need to calculate the area of the lot and subtract off the area of the house. The height in the questions is not used.

Answer 2

@Shane_B so the answer is 134?

Answer 3

Yes

Answer 4

the unit is meters? or m^2?

Answer 5

m^2

Answer 6

why is the height not being used?

Answer 7

Since you're subtracting m^2 from m^2, the answer must be in m^2 :)

Answer 8

Because you don't need the height to calculate area....who cares how tall the house is? It takes up the same area on the lot.

Answer 9

ah ok.

Answer 10

it says the lot has height

Answer 11

trapezoid HAHAAHA no?

Answer 12

i believe it's another trapezoid lol. this doesn't make sense

Answer 13

what do you think @sh

Answer 14

Yea,..I don't know why it says the lot has height. The question ends up asking "Find the area not covered by the house." That can be calculated without any heights.

Answer 15

if the lot is shaped like a trapezoid...

Answer 16

yea it could be

Answer 17

i'm sensing a theme here lol

Answer 18

Ahh...you could be right. I was thinking 3D height...not a 2D trapezoid. At any rate, if it's a trapezoid calculate the area of that and subtract off the area of the house.

Answer 19

my dream house is trapezoid shape :))

Answer 20

hehe

Answer 21

you got it from here, simon?

Answer 22

i got 22 m^2

Answer 23

I got 18m^2

Answer 24

me too. 18 as well

Answer 25

i will try again

Answer 26

alright

Answer 27

area of trapezoid = 184?

Answer 28

\[\large A_{lot}=\frac{1}{2}(b_1+b_1)h=\frac{1}{2}(10m+26m)(8m)=144m^2\]

Answer 29

guys! i'm so sorry. it is 20 not 10 x(((

Answer 30

my mind is confused and i am hungry.

Answer 31

sorry

Answer 32

oh.

Answer 33

\[\large A_{lot}=\frac{1}{2}(b_1+b_1)h=\frac{1}{2}(20m+26m)(8m)=184m^2\]

Answer 34

and then the other one is 126

Answer 35

Yep....so 184-126 m^2

Answer 36

58!

Answer 37

yup

Answer 38

I think we have a winner ;)

Answer 39

hayyy.. thanks you guys!

Answer 40

no problem :D
