Answer:
Area of the lawn = Area of outer rectangle - Area of inner rectangle. --- (1)
Measure of outer rectangle = length
= 90+5+5=100m.
Width = 40+5+5=50m
Area of outer rectangle = length * width
= 100 * 50
= 5,000 sq.m.
(2)
Area of inner rectangle is given directly = 90 * 40
= 3,600 sq.r (3)
Substitute (2) and (3) in (1), we get
Area of the Lawn = 5000m - 3600
= 1,400 sq.m.
