Question

help elase

Answer 1

it says a figure is made of a right triangle and a parallelogram, but as i see it is made of a rectangle and a parallelogram (that has an altitude of 8 units)

Answer 2

lets look at the 2 shapes:

You got a rectangle 12.6cm by 10cm, and this shouldn't be a problem to find this rectangle.

then a parallelogram, is what you have to explore a bit more carefully.
\(\large\color{slate}{ {\rm A_{ parallelogram }}={\rm Altitude}\times{\rm Base} }\)

Answer 3

oh, my bad.

Answer 4

your shape says to be a parallelogram, but you need to find the average length and multiply times the altitude.

Answer 5

okay

Answer 6

it is actually a trapezoid (w/ a rectangle)

Answer 7

what can you tell or/and ask me so far?

Answer 8

so its add all side or times all sides?

Answer 9

thats with times highet times length right?

Answer 10

yes, the rectangle is height times length.

Answer 11

so got that part with a rectangle?

Answer 12

yes

Answer 13

k, now you have a trapezoid, i will draw it, but i will flip it for you to better see.

Answer 14

okat

Answer 15

yes, it is a parallogram my bad.

Answer 16

i thought that 14cm is the entire bottom side, but it is not.

Answer 17

the dashed line of 8cm is an altitude, so the other part from that line to the corner (going to the left from the dashed line, on the bottom side of the parallelogram) is (can call it x, that part doesn't mater for us.)

Answer 18

okay

Answer 19

oh so i should do with times highet times length first?

Answer 20

you know that parallelogram's area is length times altitude.
your altitude is 8, and length is 20 (as you can see on my or your picture).

the part of 14 and the x is what you should disregard.

Answer 21

okay

Answer 22

so can you find the area of a parallelogram for me?

Answer 23

if you don't know how, please ask

Answer 24

okay

Answer 25

so 197.8?

Answer 26

no

Answer 27

your altitude is 8cm, and the base is 20

Answer 28

ik this

Answer 29

sure, go ahead:D

Answer 30

oh you are multiplying 20 times 8, that is correct,

but what you wrote after "OR" WOULD MEAN THAT YOU ARE DIVIDING 20 BY 8.

Answer 31

Area (parallelogram) = (Altitude) times (Base)

Answer 32

160

Answer 33

yup

Answer 34

so add this (the area of a parallelogram that you found to be 160) + the area of the rectangle

Answer 35

what was the area of a rectangle, do you know?

Answer 36

yes

Answer 37

What was it?

Answer 38

sorry lag

Answer 39

it;s fine

Answer 40

umm i would say 160 but thats the area for the other one so i would say

Answer 41

i think 1260

Answer 42

wait, you are adding 160 (area of a parallelogram) + 126 (the area of a rectangle) correct?

retry please.

Answer 43

holdo n

Answer 44

when you add you get 412
