Question

Exercise 16 B composite mathematics grade 8 . Question 1 find the area of the polygon

Answer 1

Answer:

69cm²

Step-by-step explanation:

Area of triangle AED = 1/2 × b × h

= 1/2 × 6 × 8

= 24cm²

Area of trapeium BCDE = 1/2 ×( b1 + b2 ) × h

= 1/2 × (12+6) × 5

= 1/2 × 18 × 5

= 45cm²

Area of polgon = 24cm² + 45cm² = 69cm²
