A rectangular field measures 227 by 56 yards. How far is it to walk from one corner of the field to the opposite corner? How far
GaryK [48]

Answer:

233.8 Yards

Step-by-step explanation:

Given that,

Length of a rectangular field, l = 227 yards

Breadth of a rectangular field, l = 56 yards

Let x is the distance from one corner of the field to the opposite corner. It can be calculated using Pythagoras theorem,

x=\sqrt{l^2+b^2} \\\\x=\sqrt{(227)^2+(56)^2} \\\\x=233.8\ \text{Yards}

So, the distance from one corner of the field to the opposite corner is 233.8 Yards.

Joan needs to estimate the size of her bedroom so that she can buy enough paint to cover the walls. Two of the walls measure 2.8
labwork [276]

The total area of the room is 37.6376 and the no. of cans required to paint the wall is 3 cans.

The measurement of two of the walls is 2.86 metres and 3.16 metre

Area of the two walls = 2(length x breadth)

Area = 2(2.86 x 3.16) = 18.0752 m²

The measurement of the other two walls is 2.86 metres and 3.42 metres

Area of the two walls = 2(length × breadth)

Area = 2(2.86 × 3.42) = 19.5624 m²

Total area = 18.0752 + 19.5624 = 37.6376 m²

If one can of paint can cover 15 m², the no. of cans required to paint the bedroom will be

No. of cans = Total area/Area covered by one can of paint

No. of cans = 37.6376/15 = 2.5091 = 3 cans (approx.)

What are the weight of the horses on the farm? Is that a statistical question?
Marizza181 [45]
Based on my information, I believe that this would actually be a statistical because the question contains extra information that would help you narrow down the answer. The question could have been a lot easier, such as: "how much do horses weigh", but it does not, it
contained extra data that would help answer the question to the point.
