STEP-BY-STEP SOLUTION:
Let's solve this problem step-by-step.
As posters are generally rectangular in shape, we will establish the formula for the area of a rectangle which we will be using as displayed below:
Area = height × width
Now let's find the area of the postwr using the above formula.
Height = 2 feet
Width = 0.7 feet
Area = height × width
Area = 2 × 0.7
Area = 1.4 square feet
ANSWER:
Therefore, the answer is:
The area of the poster is 1.4 square feet.

Answer:
The width measures 2.5 cm
Step-by-step explanation:
Area of triangle = Area of rectangle
1/2 bh = wh
1/2(5)(6) = w(6)
1/2(30) = 6w
15 = 6w
15 ÷ 6 = w
2.5 = w
Answer:
My example:
1. Get the equation in the form y = ax4 + bx + c
2. Calculate -b / 4a. This is the x coordinate of the vertex
3. To find the y coordinate of the vertex, simply plug the value -b / 4a into the equation for x and solve for y.
Step-by-step explanation:
y=2x^2 -16x +30
vertex: ( 4, -2)
Focus: (4, -15/8)
Axis of symmetry: x = 4
Directrix: y = -17/8
Answer:
$24
Step-by-step explanation:
calculate 20% of $30 and subtract the discount from the cost price
20% = 
= 0.2, hence
discount = 0.2 × $30 = $6
buying price = $30 - $6 = $24
