Answer 1

Answer:

(i) 65 m², (ii) 45.5 m², (iii) 19.5 m²

Step-by-step explanation:

(i) Area of trapezium ACDE:

= (1/2) * (AC + DE) * h

= (1/2) * (13 + 7) * 6.5

= 65 m²

(ii) Area of parallelogram ABDE:

= b * h

= 7 * 6.5

= 45.5 m²

(iii) Area of triangle BCD:

= (1/2) * BC * h

= (1/2) * 6 * 6.5

= 19.5 m²

Hope it helps!

Answer 2

Step-by-step explanation:

area of trapezium ACDE=1/2(sum of parallel sides) *height. = 1/2*(7+13)*6.5. = 1/2*20*6.5=65m.

area of parallelogram ABDE=base*height. =6.5*7=455sqm.

the area of triangle BCD=1/2*base*height. =1/2*6*6.5=19.5sqm. done
