Question

4 Calculate the area of the shaded region from the adjoining figure.
​

Answer 1

Answer:

2464m^2

Step-by-step explanation:

for calculating length,

60-4=56

now 56/2=28m

for width,

50-6=44

now 44/2=22m

so the area of that shaded rectangle is 28*22=616m^2

there are 4 rectangles.

so 4*616=2464m^2

Answer 2

Step-by-step explanation:

1 . First we have to, find the area rectangle

shaped figure=length × breadth

2 . 60×50=3000m sq

3 . To find the area of the horizontal rectangle

is =60×6=360m sq

4 . Area of vertical triangle =50×4=200m sq

5 . Total area of the vertical & horizontal paths

= 360+ 200-24= 536sq m

(Here 24 is subtracted from the sum of the areas of the paths becoz Here in the two paths we have to line in those paths.. After lining we will see that the two lines intersect in those paths it is the common area for the both the paths that's why it (24…)is subtracted

6 . 3000-536=2464sq m is the area of the shaded portion..
