Answer:
15200cm^2
Step-by-step explanation:
we can separate this into 2 equivalent triangles , 2 equivalent rectangles, and 1 extra rectangle.
the area of a triangle is 1/2b*h so 40*60*1/2=1200
we have 2 of these triangles so the area of the triangles in total is 2400.
next, the 2 equivalent rectangles. the area of a rectangle is b*h is 80*50= 4000
we have 2 so the area of these rectangles in total is 8000.
lastly we have one more rectangle 60*80=4800.
then we add all these up 2400+8000+4800= 15200
add unit
15200cm^2
and we're done

Ok so suppose the theory that if you add two sides of a triangle together it will be more than the remaining side but it has to work for all three sides so the two sides 10+8=18 so the number has to be less than 18 but the number also has to be more than 3 because 8+3=11 and 11 is larger than ten. the answer is
The value of RS in the line segment is 20
To solve for RS :
From the line segment attached :
The information given is :
RS = 3x - 16
ST = 4x - 8
RT = 60
RT = RS + ST
60 = 3x - 16 + 4x - 8
60 = 7x - 24
60 + 24 = 7x
84 = 7x
Divide both sides by 7
84/7 = x
x = 12
RS = 3x - 16
RS = 3(12) - 16
RS = 36 - 16
RS = 20
HENCE, RS = 20

2n + n/2 = 10
4n/2 +n/2 =10
5n/2 = 10
5n = 20
n = 4
