Question

Exercise 11.3

fig
1. Find the area of the field shown below
(al measurements are in m.)
2. Find the area of
the given polygon​

Answer 1

Answer:

sorry i am very weak in this chapter

Answer 2

in triangle ABG

area of triangle= 1/2 ×length ×height

= 1/2×30×50

=15×5p

=750msq

in ∆ AFE

same as above formula

= 1/2×60×40

=120m sq

in ∆BCG

same as above

=1/2×30×60

=900m sq

in triangle ECD

same as above

=1/2×40×20

=400m sq

add ∆ABG+∆AFE+∆BCG+∆ECD

= 750+120+900+400

=2170m sq

always give an formula in each ∆ to understand if not possible give fig1 ,2 etc

I hope u understand
