Question

from the adjoining diagram, calculate:
1) the area of trapezium ACDE
2) the area of parallelogram ABDE
3) the area of triangle BCD

Answer 1

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

Answer 2

Area of ACDE =65cmsquare .Area of ABDE =45.5cmsquare and Area of BCD =19.5cmsquare
