Answer» Step-by-step EXPLANATION: Let the side of the isosceles triangle be x GIVEN 3/2 x +x +x=42cm 3x/2 + 2x =42 (3x+4x)/2=42 3x+4x=84 7x=84 x=12cm side=12cm BASE=18cm The height(altitude) of an ISOS. triangle divides it into two rt triangles in a rt. triangle, base²+height²=hypotenuse² thus, 9²+h²=12² h=√12²-9² =√144-81 =√63 =3√7cm area =1/2 x base x height =1/2 x 18 x3√7 27√7 cm² HOPE YOU GOT THIS IF YES THEN BE THE FIRST TO MARK IT AS THE BRAINLIEST FOR SURE ..!!! |
