Question

WILL GIVE 30 POINTS TO WHOEVER SOLVES THIS

Answer 1

Answer:

142 square meters

Step-by-step explanation:

     Big rectangle    Area =  LxW  =      18 x9= 162

White triangle  Area   A =   (ab)/2      legs 5 and 8   ( 18-10= 8 )

= (5x8)/ 2  = 20

Subtract white triangle from green  rectangle

 162-20 = 142

    OR

area  left  rectangle    LxW     10x9 = 90

area  right rectangle    LxW       4x8 =32

area green triangle ( sides 5 an8 )   (ab)/2  =   20

90+32+20 =  142

Answer 2

151 meters² is the correct answer!

First, find the area of the rectangle:

10 x 9 = 90

Second, find the area of the triangle:

9 x 18 = 162

162 ÷ 2 = 81

Third, find the area of the triangle "inside" of the rectangle and subtract it from the bigger triangle:

9 - 5 = 4

4 x 10 = 40

40 ÷ 2 = 20

Then it all comes together:

90 + (81 - 20) = 151

(BTW, it's actually 15 points because 30 points gets split between two people.)
