Question

Matematika tentang Luas Daerah Yang diraster.
kalau jwbnya serius nnti sya tndai sbgai TERBAIK

Answer 1

1. L1 = 1/2 . a. t
= 1/2 . 14. 20
=140

L2 = 1/2 (nr²)
=1/2 (22/7 . 7²)
=1/2(154)
=77

L = L1 + L2
=140 + 77
=217

2. L persegi = 21.21
=441

L1 = 1/2 (nr²)
=1/2(22/7. 7²)
=1/2(154)
=77

L2 = 2 ( 1/2. a. t)
=2(1/2. 14 . 10,5)
=2(73,5)
=147

L = L persegi - ( L1 + L2 )
=441 - ( 77+147)
=441-224
=217
