Step-by-step explanation:
area of triangle=1/2bh=1/2*24*14=168cm2 area of one circle=πr2= 49π at point B=360/4=90 then 49π/4 is area of b. at point A= 360/6=60 49π/6 is area of A. at point C=360/12=30 49π/12 is area of C. area of shaded portion = area of triangle-area of vertices atA, B, C =168-(49π/4+49π/6+49π/12)=168-(39+26+13)=168-78=90 cm2. this areas at vertices at A B and C are rounded off in real they are decimal points
