What is the area of this quadrilateral(Please show a step by step process)
Tresset [83]

Answer:

40ft

Step-by-step explanation:

What you need to know is the formula for the air of a rectangle:

the long side * the short side.

First calculate the area of the rectangle in the middle: 3*8=24ft

Then we are left with two right-angled triangles, one on the left and one on the right. If we juxtapose them, we realize that it forms a rectangle whose large side measures 8 and the small 2 so 2*8=16ft.

Finally, just add the area of the middle rectangle with the area of our rectangle formed by the two triangles on the right and on the left. So 16+24=40ft

Schach [20]

Answer:

Number of cookies sold is 2000 and number of cupcakes sold is 1500

Step-by-step explanation:

Let number of cookies be x

and number of cupcakes be y so

x+y=3500

Cost of one cookie is $0.75

Cost of one cupcake is $2

0.75x+2y=4500

x+y=3500 \times 2

2x+2y=7000

-1.25x=-2500\\\Rightarrow x=\dfrac{2500}{1.25}\\\Rightarrow x=2000

y=3500-x=3500-2000\\\Rightarrow y=1500

Number of cookies sold is 2000 and number of cupcakes sold is 1500.
