      52a^2 itwas a fairlyfairly easy question

      52a^2 you had to use Pythagoras theorem

      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

      Yeah I used the formula too and got the height for 4a

      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?? :'(

      exam

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