Question

Luasnya ya plis
bsok di kumpul

Answer 1

T = (24-10)/2
  = 14/2
  = 7
b = 7 + 10
   = 17
luas = ( 1/2 x(a+b) x t) + ( 1/2 x a x t)
       = ( 1/2 x ( 10+17) x 10) + ( 1/2 x 7 x 10)
       = ( 17 x 5) + ( 7 x 5)
       = 85+35
       = 120 cm²

Answer 2

L = 1/2×(a + b)×t
=1/2×(10+14)×10
=1/2×24×10
=12×10
=120 cm2
semoga membantu
