Answer:

Step 2: 47

Step 3: 84

Step 4: 114

Step-by-step explanation:

Step 2: The width is 21, and the length is 36.

Sum is addition, so it would be 21 + 36.

21 + 36 = 47

Step 3: 47 x 2 = 84

Step 4: Perimeter is all around, whilst area is on the inside. The length is 21, so it is 21 + 21. 21 + 21 is 42. The width is 36, so it is 36 + 36, which is 72. 72 + 42 = 114.

Answer:

option B. MB/AM=NC/AN

Step-by-step explanation:

we know that

The Triangle Proportionality Theorem states that if a line is parallel to one side of a triangle and it intersects the other two sides, then it divides those sides proportionally

In this problem

MN is parallel to BC

MN intersect AC and divide into AN and NC

MN intersect AB and divide into AM and MB

Applying the Triangle Proportionality Theorem

$\frac{AN}{NC}=\frac{AM}{MB}$
