Question 1 Unsaved
A bird refuge is shaped like a parallelogram with a base of 650 m and a height of 450 m. Volunteers want to install birdhouses on the refuge. They divided up the refuge into regions, each approximately 25 m by 25 m, and plan to install one birdhouse in each region.

Which estimate best approximates the number of birdhouses that the volunteers will install on the refuge?

Question 1 options:

45

235

470

Answer 3

For a problem like this, you'd just need to find the total area of the parallelogram, (base times height). Then, find the area of each of the 25 by 25 sections. Divide one by the other to calculate how many 25 by 25 sections fit in the total area.

Answer 4

Oh

Answer 5

So how would I work it out-like where would I start first?

Answer 6

First, you'd want to calculate the total area of the bird refuge. You're given the base and the height, so you just need to multiply these values together to get the area, since the shape is a parallelogram.

Answer 7

Then you'd just find out how many times (25 * 25) can go into an area of that size.

Answer 8

650*450=292,500

Answer 9

Great. So how many 25*25 regions can fit into the area of 292,500?

Answer 10

25*25=625, I find how many times 625 can pile to amount that number?

Answer 11

Yep, that's the idea

Answer 12

I would say 470 times. But that amounts to 293,750

Answer 13

Right. It's not exact, but the question just asks for the best approximation. So 470 would actually be the closest.

Answer 14

Okie dokie, that makes sense. Thank you very much sir.

Answer 15

No problem, I'm glad I could help
