✔ 最佳答案
1a)$1/2mp1b)11mp
2)12*11+7y=237
132+7y=237
7y=237-132
7y=105
y=15
3)3(x+2x)=72
3x+6x=72
9x=72
x=8
So the perimeter of the larger triangle=2*8=16cm.

1a .$ m divide by 2
1b . mp + 20p ( m divide by 2 )
2 . 11 times 12 + 7y = 237
3 . 唔識
1b . mp + 20p ( m divide by 2 )
2 . 11 times 12 + 7y = 237
3 . 唔識
