<u>Answer-</u>

1- D. 13.6 cm²

2- A. 4.4 cm²

<u>Solution-</u>

We know that,

$\text{Area}= \frac{1}{2}\times \text{Base}\times \text{Height}$

Here,

Base = 3.4 cm

Height = 8 cm

Applying the formula,

$\text{Area}= \frac{1}{2}\times 3.4\times 8 = 13.6\ cm^2$

Here,

Base = 4.4 cm

Height = 2 cm

Applying the formula,

$\text{Area}= \frac{1}{2}\times 4.4\times 2 = 4.4\ cm^2$

Answer:

Step-by-step explanation:

This is a proportional question. If you learn how to keep things together, they are not only easy to do, they are mechanical: they are all done exactly the same way.

tanks of gas different tanks of gas

========== = ================

hours different hours.

initial tank of gas = 3/4 tank

initial hours = 9/2 = 4.5 hours

final tanks of gas = X

final time = 12 hours.

Solution

3/4 x

==== = ==============

4.5 12

Cross multiply

4.5x = 12*3/4 Combine the right

4.5x = 36/4 Simplify

4.5x = 9 Divide both sides by 4.5

x = 9/4.5

x = 2

So she will need 2 tankfuls.
