Luas taman = Luas tanah - Luas rumah
*L rumah = 20 x 24 = 480 m²
*L tanah
= jml sisi sejajar : 2 x t
= (a + b) : 2 x t
t = 30
b = 94
a = 94 - x
# 50² = 30² - x²
x² = 2500 - 900
x² = 1600
x = 40m
a = 94 - 40 = 54 m
L tanah = (54 + 94) : 2 x 30
= 148 x 15
= 2220 m²
Luas taman = 2220m² - 480 m² = 1740 m² (B)
