A rectangular piece of land measuring 100 m by 90 m has an area of 40 m by 80 m planted with beans and another area of 30 m by 30 m planted with sukumawiki. The rest of the land has maize. Find the area under maize.​

Answer 1

4900m²

Explanation:

Area of rectangular plot = lxb

=100x90

=9000m²

Area of beans = lxb

=40x80

=3200m²

Area of sukumawiki = lxb

=30x30

=900m²

Area of maize = Total area - Area of beans - Area of sukumawiki

=9000-3200-900

=4900m²
