Answer:
The area of the lawn is 68
.
Explanation:
Area of lawn = Area of garden - (Area of triangle + Area of trapezium)
Area of garden = length x width
= 14 x 10
= 140
Area of triangle =
x base x height
=
x 3 x 8
= 12
Area of trapezium =
(a + b) h
=
(5 + 7) 10
= 60
So that;
Area of lawn = 140 - (12 + 60)
= 140 - 72
= 68
The area of the lawn is 68
