Question

The figure is drawn on centimeter grid paper. Find the perimeter of the shaded figure to the nearest tenth.


A. 17.6 cm
B. 10.8 cm
C. 15.6 cm
D. 18.0 cm

Answer 1

look at the triangle in the bottom right
the bottom edge is 3, the vertical edge is 4
What is the length of the hypotenuse

Look at the triangle top right
the vertical edge is 3
the top edge is 7
use Pythagoras to find the hypotenuse

the other two edges are easy to see their length

add the 4 edges to get the answer

Answer 2

so c right???

Answer 3

YOu seem to have guessed that rather quickly

do you want to go back and work it out?

Answer 4

i had it worked already just making sure it was right cause i kinda suck at this lol

Answer 5

show me the work to see where you went wrong

Answer 6

i used quick memo on my phone kinda gone already

Answer 7

Well you need to do it again as you made a mistake

Answer 8

i think you made a mistake mr

Answer 9

@iGreenHacked you know how to do this?

Answer 10

I KNOW how to do it

I want YOU to know how to do it

You need to use Pythagoras to find the 2 sloping sides

One of them is trivial , the other needs a calculator.

You see the other 2 sides are 1, and 4

ADD the 4 sides - it is not C

Answer 11

its not b either

Answer 12

I am not going to confirm or deny any more guesses
just DO the work

work out the two hypotenuse, using Pythagoras
