The area is ___ square units

suter [353]

Answer:

392 square units

Step-by-step explanation:

We can make 2 right trapezoids out of this shape.

The area of a trapezoid would be 1/2×(b1+b2)×h or (b1+b2)×h ÷ 2.

If we do 1 half it would be 1/2×(14+14)×14 = 196

Now if we multiply by 2 (because we have 2 trapezoids) it would be 392.

Anybody can help me with this question please

lord [1]

Answer:

2 cookies per dollar

Step-by-step explanation:

You can take any point on the line, turn it into a fraction and simplify.

For example: 4 cookies cost $2.

4 cookies per 2 dollar is 2 cookies per 1 dollar (divide by 2)

If you take another point, e.g., 14 cookies for 7 dollar, you'll be dividing by 7 to simplify and get the same answer.
