Question

Am I right if not plz explain. See pic below.

Answer 1

No, that's incorrect.

The area is just \(\sf A =bh\).

Answer 2

ok but could you help me get to the answer without doing the work?

Answer 3

14 is the base..12 is the height..all you have to do is multiply. But it seems like they want you to split it into 2 triangles and a rectangle, like the question states.

Answer 4

u want me to show you what the lesson says?

Answer 5

This is in the lesson

Answer 6

To find the length of the rectangle, just subtract 14 - 3.

Answer 7

What did you get?

Answer 8

11

Answer 9

Yes..so we have two triangles, and one rectangle.

2 traingles:
b = 3
h = 12

Area of a triangle:
\(\sf A = \dfrac{1}{2}bh\)

Rectangle:
l = 11
w = 12

Area of a rectangle:
\(\sf A = lw\)

Plug the values into the equations and simplify, can you do that?

Answer 10

So do you do 1/2 of 12= 6 x 3= 18? Then do 11 x 12 = 132. So 132 + 18 = 150?

Sorry I don't really understand how s math just yet :/

Answer 11

Sorry I don't know how to do this math just yet :/ ***

Answer 12

Yes..but remember we have 2 triangles, not just one.

2 * 18 = ?

Answer 13

36

Answer 14

Yes, and 36 + 132 = ?

Answer 15

168

Answer 16

Correct, that's the area of the parallelogram.

Note that if we just multiplied the base times the height we would've gotten the same answer.

14 * 12 = 168

Answer 17

Ok thank you!!! :) now I understand

Answer 18

No problem.
