If they already have $175, they need $250 more dollars. At $8 a water bottle, they would need to sell at least 32 more bottles.

1.What is the area of this parallelogram?
dexar [7]

Question 1: Option D

Area of the parallelogram = 132 cm²

Question 2: Option B

Area of the parallelogram = 3.60 ft²

Solution:

Question 1:

Base of the parallelogram = 6 + 5 = 11 cm

Height of the parallelogram = 12 cm

Area of the parallelogram = Base × Height

                                           = 11 × 12

Area of the parallelogram = 132 cm²

Option D is the correct answer.

Question 2:

Base of the parallelogram = 1.9 + 0.5 = 2.4 ft

Height of the parallelogram = 1.5 ft

Area of the parallelogram = Base × Height

                                           = 2.4 × 1.5

Area of the parallelogram = 3.60 ft²

Option B is the correct answer.

In this diagram, ABAC – AEDF. If the<br> area of ABAC = 6 in?, what is the<br> area of AEDF?
shepuryov [24]

Answer:

2.7 in²

Step-by-step explanation:

similar triangles have the same angles, and all side lengths (or other distances) of one triangle have the same scaling factor to the side lengths of the other triangle.

so, we know the relation between the 2 baselines is 2/3, as this is the factor to turn the baseline of the large triangle into the baseline of the smaller triangle.

in other words

EF = BC × 2/3

2 = 3 × 2/3

correct

how do we calculate the area of a triangle ?

Area = baseline × height / 2

from BAC we know

Area = 6

baseline = 3

height = ?

6 = 3 × height / 2

12 = 3 × height

height = 4

aha !

now, EDF has a height too that we need to calculate is Area. and this height has the same scaling factor compared to the larger triangle as the side lengths : 2/3

so, for EDF we know

Area = ?

baseline = 2

height = 4 × 2/3 = 8/3

therefore, the area is

Area = (2 × 8/3) / 2 = (16/3) / 2 = 8/3 = 2.66666... ≈ 2.7

the shirt answer would be :

we know from the 2 baselines that the scaling factor for each distance is 2/3.

for the area we need to multiply 2 distances, so that means we have to multiply both by 2/3. and so on the formula for the area we have to use 2/3 × 2/3.

2/3 × 2/3 = 4/9

=>

Area small = Area large × 4/9 = 6 × 4/9 = 24/9 = 8/3 ≈ 2.7
