can someone help me with 5 question

OpenStudy (anonymous):

Yes I can What are the ?

OpenStudy (anonymous):

Find the area of the figure. Assume the figure is made up of parallelograms. A. 275 cm² B. 375 cm² C. 550 cm² D. 625 cm²

OpenStudy (anonymous):

OpenStudy (anonymous):

2 figures, just simply get the area of each one ( length times width), and add them up together.

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

So you would get answer A

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

Your welcome! what is your next ?

OpenStudy (anonymous):

Find the area of the figure. Assume the figure is made up of triangles. A. 98 cm² B. 147 cm² C. 196 cm² D. 294 cm²

OpenStudy (anonymous):

Just break the figure along the horizontal centreline - you have 2 identiocal triangles (height * base)/2 is the area of each

OpenStudy (anonymous):

OpenStudy (anonymous):

@Vampirelove28 so the answer is a

OpenStudy (anonymous):

Yes you are right!

OpenStudy (anonymous):

See you are getting it now! so what is the next ?

OpenStudy (anonymous):

What is the area of the figure? A. 128 km² B. 160 km² C. 192 km² D. 320 km²

OpenStudy (anonymous):

First, find the area of the rectangle and then find the area of the triangle and add the two areas together.

OpenStudy (anonymous):

So the answer is D

OpenStudy (anonymous):

Next ?

OpenStudy (anonymous):

What is the area of the shaded part of the figure? A. 112.5 mm² B. 225 mm² C. 450 mm² D. 675 mm²

OpenStudy (anonymous):

First, we find the area of the triangle. \[.5\times30\times30=450\]Now the area of the square. \[15^{2}=225\]Now to subtract the area of the square from the triangle. \[450-225=225 mm ^{2}\]

OpenStudy (anonymous):

So the answer is B

OpenStudy (anonymous):

225

OpenStudy (anonymous):

next ?

OpenStudy (anonymous):

Your right

OpenStudy (anonymous):

What is the area of the shaded part of the parallelogram? A. 288 m² B. 432 m² C. 444 m² D. 576 m²

OpenStudy (anonymous):

OpenStudy (anonymous):

hello

OpenStudy (anonymous):

Hold one sec

OpenStudy (anonymous):

i think it is a

OpenStudy (anonymous):
