Area of the square?
Junior Cert Mathematics — 11/06/16 16

What did you all get for the area of the square on he second last question?

52a^2 itwas a fairlyfairly easy question
carolinaaplasencia — 10/06/16
yeah 52
Dianas659 — 10/06/16
52a^2 you had to use Pythagoras theorem

7a² was what i got
caolanf — 10/06/16
10a squared
Aoife_9776 — 10/06/16
I got 10a^2
Abdrahim01 — 10/06/16
Got 10a^2 too I think, used pythagoras too

Square root of 7a to the power of 4 ����

i used the area of a triangle formula to get that the height was a , and the base was 6a. i then put these into pythagoras to get a hypotenuse of 7a, which i squared for the area of a square
Aoife_9776 — 10/06/16
Yeah I used the formula too and got the height for 4a

I got 10a squared

I found the theorem of Pythagoras and the height of the triangle was 4a and then the hypotenous was 52a. I square rooted 52 and got 7 as the length of the square and then the area of the square is l×w which is 42

1/2 the height multiplied by base is = to the area of a triangle so 2a multiplied by 6a is equal to12a squared.This means the height is 4 . 4a squared plus 6 a squared is 16a squared plus 36a squared = 2 multiplied by the square root of thirteen a this in turn multiplied by itself is equal to 52a squared . Well that's what I did anyway

Isn't it half the base by the perpendicular height?

Am i the only one who got 26a squared?? :'(

Sam kiely, 4a squared + 6a squared is 10a squared isn't it? It would be 16a + 36a if it was (4a) squared + (6a) squared
