Answer:

Option D. 8 units

Step-by-step explanation:

step 1

Find the area of rectangle

The area of rectangle is

A=(4)(16)=64\ units^2

step 2

Find the length side of the square with the same area of rectangle

The area of a square is

A=b^2

where

b is the length side of the square

we have

A=64\ units^2

substitute

64=b^2

take the square root both sides

b=8\ units

therefore

The length side of the square is 8 units

No. See, you can take 60 out of 156 twice and you are left with 36. This means the drive would take about 2 hours and 36 minuets. 7+2=9 30+36=66 so then you add an our the time and you get that she would arrive a few minuets afterwards. (I'm sorry if I didn't explain this very well)

Camilla, Lincoln and Ella sat a French test. The test was marked out of 200
Vladimir [108]

Answer:

Ella got the highest marks.

Step-by-step explanation:

Given that:

Camilla got 4/5 of the 200 marks.

Marks of Camilla = \frac{4}{5}*200

Marks of Camilla = 160 marks

Lincoln got 44% of the 200 marks.

Marks of Lincoln = \frac{44}{100}*200

Marks of Lincoln = 88 marks

Ella got 198 out of 200.

On comparing,

198 is the highest out of 200.

Hence,

Ella got the highest marks.
