tolong bgt ini butuh please

3. L1 (jajar genjang) = a x t
= 25cm x 17cm
= 425cm²
L2 (persegi panjang) = p x l
= 25cm x 22cm
= 550cm²
L Gabungan. = L1 + L2
= 425cm² + 550cm²
= 975 cm²


4. L1 (trapesium) = (a+b) x t
-------------
2
= 101 x 15
-----------
2
= 1.515 = 757,5 cm²
-------
2
L1 = L2. = 757,5cm²
L gabungan = 757,5cm² + 757,5 cm²
= 1.515 cm²



5. L1 (persegi panjang) = p x l
= 44cm² x 43cm²
= 1.892cm²
L2 (Trapesium) = (a+b) x t
-------------
2
= (43+15) x 38
--------------------
2
= 58cm x 38cm
--------------------
2
= 2.204.
----------
2

= 1.102cm²
L Gabungan. = L1 + L2
= 1.892cm² + 1.102cm²
= 2.994cm²



Maaf ya kalau caranya buat bingung
dan semoga benar
