1 : 1,5
(1 x 2) : (1,5 x 2)
2 : 3
2y : 3y
L = d1 x d2 x 1/2
1.200 = 2y x 3y x 1/2
1.200 = y x 3y
1200 = 3y²
1200 : 3 = y²
400 = y²
√400 = y
20 = y
maka
bilah A = 2y = 2 x 20 = 40 cm
bilah B = 3y = 3 x 20 = 60 cm
(1 x 2) : (1,5 x 2)
2 : 3

L = d1 x d2 x 1/2
1.200 = 2y x 3y x 1/2
1.200 = y x 3y
1200 = 3y²
1200 : 3 = y²
400 = y²
√400 = y
20 = y
maka
bilah A = 2y = 2 x 20 = 40 cm
bilah B = 3y = 3 x 20 = 60 cm
