Oblicz pole trapezów przedstawionych na rysunkach A) a=50 m b=20 m h=10 m B) a=9 cm b=7 cm h=6 cm

P = ( a + b) * h/2 = ( 50 m + 20 m ) * 10 m /2 = 70m * 10/2 = 350m² b) P= ( a +b) * 6/2 = ( 9cm + 7 cm) * 6 cm /2 = 16cm * 6 /2 = 48 cm²

Wzór na pole trapezu = [latex] frac{(a+b)*h}{2} [/latex] A) a = 50 m b = 20 m h = 10 m P = [latex] frac{(a+b)*h}{2} = frac{(50+20)*10}{2} = frac{70 * 10}{2} = frac{700}{2} = [/latex] 350 m² B) a = 9 cm b = 7 cm h = 6 cm P = [latex] frac{(a+b)*h}{2} = frac{(9+7) * 6}{2} = frac{16 * 6}{2} = frac{96}{2} = [/latex] 48 cm²
