Answer» Answer: Maths solution Step-by-step EXPLANATION: Solution :- 1) Area of the Δ DEI = 1/2 × Base × Height ⇒ 1/2 × 60 × 40
= 1200 SQ m 2) Area of the Trapezium EFGI = 1/2 × (Sum of the two parallel SIDES) × Height ⇒ 1/2 × (60 + 50) × 70 ⇒ 1/2 × 110 × 70 = 3850 sq m 3) Area of the Δ AFG = 1/2 × Base × Height ⇒ 1/2 × 50 × 50 = 1250 sq m 4) Area of the Trapezium ABCH = 1/2 ×(Sum of the two parallel sides) × Height ⇒ 1/2 × (40 + 30) × 80 ⇒ 1/2 × 70 × 80 = 2800 sq m 5) Area of the Δ CDH = 1/2 × Base × Height The height of this figure is not clear in the image. I THINK it is 80 m and I have assumed it 80 m. ⇒ 1/2 × 40 × 80 = 1600 sq m Total area = Area of Δ DEI + Area of the Trapezium EFGI + Area of Δ AFG + Area of Trapezium ABCH + Area of Δ CDH ⇒ 1200 + 3850 + 1250 + 2800 + 1600 = 10700 sq m So, the area of the figure ABCDEF is 10700 sq m |
