Question

Can someone please help me with this question? I will medal the person with the best answer. Thanks! Also, look at the graph along with the question.

Calculate the area of the block “N” shown.

252 mm(squared)
147 mm(squared)
267 mm(squared)
122 mm(squared)

Answer 1

ill walk you through this

Answer 2

Okay.

Answer 3

notice how you can split this into two rectangles and two triangles? like this

sorta like this this is very sloppy but you can get the idea

Answer 4

Okay I see.

Answer 5

whats the area formula for a triangle? and for a rectangle?

Answer 6

A=l*w A=(1/2)b*h

Answer 7

very good. so all you have to di is plug the numbers in and solve. so what would be the length and width of the rectangle? figure this out then just multiply the length times the width then multiply that number by 2 and ill help you once you figure that out

Answer 8

A=l*w A=5*21 A=105

Answer 9

very good and since there is two of these rectangles just multiply it by 2 and you get 210 that's the area for BOTH rectangles. not plug the numbers in for the area of the triangle

Answer 10

if youre having trouble with the equation let me know i can help you!

Answer 11

okay. A=(1/2)b*h b=(1/2)10.5*3=15.75

Answer 12

Is that right @dl9817?

Answer 13

im checking but i don't think that's correct.

Answer 14

your triangle solution is not quite correct, ill just give it to you you've tried hard :P

the correct for the triangle is 21 but since theres two identical triangles you don't need to half it if you follow me so the answer would be 42 so 42+210+252mm squared.

MEDALS PLEASE :)))

Answer 15

let me know if that was correct for you :)

Answer 16

Okay. I had got the answer 21 before but I thought it was wrong. so the answer is 252mm squared?

Answer 17

yes option (A) is correct

Answer 18

@BeccaB003 tell me if that was correct when you submit the assignment

Answer 19

Okay I will. Thanks!
