Answer:
(i) Triangle ABC and triangle ADE are similar triangles. Hence, their ratios will be same.
Ratio of DE to BC is 4:6 => 2:3
To find area, we need to raise the ratio of length to power 2
(2/3)² = 16/x
4/9 = 16/x
x = (16*9)/4
x = 36cm²
Therefore, area of triangle ABC is 36cm²
(ii) Ratio of DE to BC is 4:8 => 1:2
(1/2)² = 25/x
1/4 = 25/x
x = 25*4
x = 100cm²
Therefore, area of triangle ABC is 100cm²
I'm not sure about the third question, sorry

Answer:
4 inches
Step-by-step explanation:
The equation for volume of a rectangular prism is V=lwh, where l=length, w=width, h=height.
We are given the volume, length, and width, so let's put those in and solve for the height.
V = lwh
660.24 = 13.1*12.6*h
660.24=165.06h
660.24/165.06 = h
4 = h
<u>The height is 4 inches.</u>
Answer:
Step-by-step explanation:
That literally means the numbers '5' and '12' written like this: 5 + 12
represent the sum of 5 and 12, which is the same as 5 + 12 (because the sum is when all the numbers are added up).
So it's saying 5 + 12 equals to 17.
Do you get it?
