Given: AB || CD AB = 25m CD = 10m BC = 14m AD = 13m From point C draw CE || DA. Hence ADCE is a llgrm having CD II AE & ADIICE AE= CD= 10m CE= AD = 13m BE= AB- AE =25-10-15 m BE= 15m In ABCE BC= 14m, CE= 13m, BE = 15rr Semiperimeter (s) = (a + b + c) / 2 Semiperimeter * (s) = (14 + 13 + 15) / 2 s= 42/2= 21m s = 21m Area of ABCE=√ s(s-a)(s-b)(s-c) Area of ABCE=√ 21(21-14)(21-13)(21-15) Area of ABCE=√ 21x7x 8×6 Area of ABCE= √ 7×3× 7×2 4×2×2×3 Area of ABCE=√7×7×3×3×2×2×4 Area of ABCE= 7×3×2×2= 21x 4= 84m² Area of ABCE= 84m² Area of ABCE=√ 7×3× 7× 4×2×2×3 Area of ABCE=√7x7×3×3×2×2×4 Area of ABCE= 7×3×2×2= 21x 4= 84m² Area of BCE = 84m ^ 2 Area of Delta*B * C * E = 1/2 * b * a × altitude Area of Delta*B * C * E = 1/2 * B * E * C * L 84 = 1/2 * 15 * C * l 84 * 2 = 15CL 168 = 15CL CL = 168/15 CL = 56/5 * m Height of trapezium= 56/ 5m Area of trapezium= 1/2( sum of Il sides) (height) Area of trapezium=1/2(25+10)(56/5) Area of trapezium= 1/2(35)(56/5) Area of trapezium= 7x28=196m² Hence the area of field is 196m²

We will divide the given rhombus into two triangles, and by using Heron’s formula, we can calculate the area of triangles. Heron formula for the area of a triangle = √s(s - a)(s - b)(s - c) Where a, b and c are the sides of the triangle, and s = Semi-perimeter = Half the Perimeter of the triangle = (a + b + c)/2 A rhombus shaped field has green grass for 18 cows to graze. If each side of the rhombus is 30 m and its longer diagonal is 48 m, how much area of grass field will each cow be getting Let the longer diagonal AC divides the rhombus ABCD into two congruent triangles. For ∆ABC, a = b = 30 m, c = 48 m And Semi Perimeter(s) = (a + b + c)/2 s = (30 + 30 + 48)/2 s = 108/2 s = 54 m By using Heron’s formula, Area of ΔABC = √s(s - a)(s - b)(s - c) = √54(54 - 30)(54 - 30)(54 - 48) = √54 × 24 × 24 × 6 Area of ΔABC = 432 m2 Area of rhombus = 2 × Area of a ΔABC = 2 × 432 m2 = 864 m2 Since, number of cows = 18 The area of grass field will each cow get = (Total area of the rhombus) / 18 = 864 m2/18 = 48 m2 Thus, each cow will be getting a 48 m2 area of the grass field.
