Answer 2

Answer:

z = 8

Area of trapezoid HJKM = 69 Sq m

Step-by-step explanation:

1)

(3 + 4) + z = (4 + 8) + 3

7 + z = 15

z = 15 - 7

z = 8

2)

Area of trapezoid HJKM= Area of rectangle with dimensions 7 m and 6 m + Area of trapezoid with bases 6m, 3m and height 6 m

$= 7 \times 6 + \frac{1}{2} (6 + 3) \times 6 \\ \\ = 42 + 9 \times 3 \\ \\ = 42 + 27 \\ \\ = 69 \: {m}^{2}$
