Question

Tolong y yg no 5 d jwab yg lengkap

Answer 1

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)
