There are 4 triangles with base of 5 and height of 8.4
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 5 x 8.4 = 21 m^2
Multiply by 4 = 21 x 4 = 84 m^2
Area of the base = length x width = 5 x 5 = 25 m^2
Total area = 84 + 25 = 109 m^2
Answer:
x=1, y=-1. (1, -1).
Step-by-step explanation:
2x+3y=-1
3x+5y=-2
-----------------
3(2x+3y)=3(-1)
-2(3x+5y)=-2(-2)
-------------------------
6x+9y=-3
-6x-10y=4
--------------
-y=1
y=-1
2x+3(-1)=-1
2x-3=-1
2x=-1+3
2x=2
x=2/2
x=1
