The area of the arrow given in the figure is 610 square cm

<h3>Area of composite figure</h3>

The given figure is made up of rectangle and triangle. The area is expressed as:

Area = Area of rectangle + area of triangle

Substitute the given parameters

Area of the arrow = (15*20) + 0.5(31 * 20)

Area of the arrow = 300 + 310
Area of the arrow = 610 square cm

Hence the area of the arrow given in the figure is 610 square cm

2x + 3y = 26 3x + 5y = 40 find x and y I will give brainliest

Yuki888 [10]

Answer:

x = 10 and y = 2

Step-by-step explanation:

multiply first equation by 5 and 2nd equation by 3 then subtract equation 1 and 2, we get,

10x+15y= 130

9x+15y=120

( -) (-) (-)

x= 10

substituting the value of x in equation 1 we get

2x + 3y = 26

2*10 + 3y = 26

3y = 26-20

y =6/3

y= 2.i hope this helps
