L = 1/2 x a x t
= 1/2 x 40 x 30
= 600 cm²
panjang sisi miring = √a²+b²
= √40²+30²
= √160+90
=√250 = 50 cm
KΔ = a + b + c
= 40 + 30 + 50
= 120 cm
L permukaan = 2 x La + ( K x t )
= 2 x 600 + ( 120 x 83 )
= 11.160 cm²
3.
La = s x s
= 16 x 16
= 256 cm²
K = 4s
= 16 x 4 = 64 cm
L = 2 x La + ( K x t )
= 2 x 256 + ( 64 x 25 )
= 512 + 1600
= 2112 cm²
4.
La = s x s
= 37 x 37
= 1369 cm²
K = 4s
= 37 x 4 = 148 cm
L = 2 x La + ( K x t )
= 2 x 1369 + ( 148 x 54 )
= 2738 + 7992
= 10730 cm²
klo puas kasih solusi terbaiknya donk........ hehehe
