tolong ya pakai cara

Luas seluruh
600  = 2 x (3/4 lingkaran) + persegi
        = (2 x 3/4 x pi x r x r) + (s x s)
        = (3/2 x 22/7 x r x r ) + (r x r) 
        = (r x r) x (33/7 + 1)
        = (r x r) x ([tex] \frac{33+7}{7} [/tex]
        = (r x r) x 40/7
r x r = 600 : (40/7)
       = 105

Luas persegi
= s x s
= r x r
= 105 cm2
