(a) Whats the area of a rectangular field is 3888 m. If the length of the field is 72 m, what is its width?

(b)The perimeter of a rectangular painting is 374 cm. If the width of the painting is 88cm, what is its length?

Answers

Answer:

part a is 54            part b is 99

Step-by-step explanation:

72 x ? =3888

x=54

374 is the perimeter. You have a side that is 88cm so the opposite side will be 88 cm as well. 374-176=198

so between the last 2 sides we have 198. The sides will be equal so you just divide it by 2  

so the top and bottom of the rectangle are 99 and both sides are 88

twenty-nine to the wth

that's my question I dont get please help ​

Answers

You would write it as 29^w :) mark me brainliest!

Answer:

I would assume that there is more to this question somewhere on the paper. w seems to be the variable you have to find. Check if you have any more info near that question that would help you find the value of w, so that you can find out what 29 to the power of w is.

There should be an equation somewhere to solve for the value of w.

If that is the only information provided for that question, then it seems like a typo, I guess.

Answer:  80 cubic feet

=================================================

Explanation:

This tent is a triangular prism. We have two congruent triangles in front and back. Let's stand the triangular prism up so that the triangle forms the base, or floor, of this figure.

The area of the base triangle is 5*4/2 = 20/2 = 10 square feet. I used the formula base*height/2 to get the area of a triangle.

Once we know the area of the base of the prism, we multiply that by the height of the prism, which is the 8 ft. So we get 10*8 = 80 cubic feet of volume.
