Answer:

A) The width is 12 cm; the average time is 3 minutes

Step-by-step explanation:

$\frac{5}{3}= \frac{20}{y}$

Cross multiply.

5 × y = 3 × 20

5y = 60

5y ÷ 5 = 60 ÷ 5

y = 12

The width is 12 cm. Moving onto the time.

$\frac{12}{4} =\frac{y}{1}$

Cross multiply.

4 × y = 12 × 1

4y = 12

4y ÷ 4 = 12 ÷ 4

y = 3

The time is 3 minutes.

I need help on number 8 please

Well, the area of a trapezoid is A = ( $b_{1}$ + $b_{2}$ ) * h * 1/2 so you can use the area of a parallelogram, which is A = l * w, by splitting the trapezoid into 2 triangles and one rectangle. So you'd use A = l * w for the rectangle and A = 1/2bh for the triangles. You'd get the same answer!
