Luas gambar tersebut adalahh????

L1 =
$= p : times l \ = 15 times 20 \ = 300 : cm {}^{2}$

L2 =
$= p times l \ = 50times 30 \ = 1500 : cm { }^{2}$

L3 =
$= frac{1}{2} times a times t \ = frac{1}{2} times 35 times 20 \ = frac{1}{2} times 700 \ = 350 : {cm}^{2}$

Luas Keseluruhan =
$= l1 + l2 + l3 \ = 300 : {cm}^{2} + 1500 : {cm}^{2} + 350 : {cm}^{2} \ = 2150 : {cm}^{2}$
