ABC is scalene triangle base and height is 6m and 4m respectively. if the sector of radius 2m are cut from triangle then find the area of remaining portion​

Answer»

area of TRAINGLE=1/2×base×height1/2×6×46×212cm²area of sectorA=πr²∅1st/360⁰------Eq(I)area of sector B=πr²∅2nd/360⁰-----(ii)area of sector C=πr²∅3rd/360⁰----(III)area of shaded region=area of traingle-area of three sector12cm-(πr²∅1st/360⁰ +πr²∅2nd/360+πr²∅3rd/360⁰)12-{πr²/360 (∅1st+∅2nd +∅3rd)(by taking πr²/360 common)but we see that ∅1st,∅2nd and ∅3rd is also the angle of traingle and we know that sum of all angles of ∆=180⁰12 - {πr²/(∅1st+∅2nd+∅3rd)}/36012-{22/7 ×2²(180⁰)}/360⁰12- {22/7 ×2×2×1}/212- {22/7×2}12-44/7(84-44)/740/75.714cm²please MARK me as brainlist
