The perimeter of the rectangular playing field is 320 yards. the length of the field is 4 yards less than triple the width. what
fgiga [73]
Let the width be X
Then the length is X + 70
The perimeter is the sum of all sides
There are 2 widths (left side and right side) and 2 lengths (top and bottom)
Perimeter = 2 * width + 2 * length
Perimeter = 2 * X + 2 * (X+70)
Perimeter: 2 X + 2 X + 140 = 380
4 X = 380-140
4 X = 240
X = 240 / 4
X = 60
Width = 60 - the smaller of two sides
Length = X + 70 = 60 + 70 = 130 - the larger of two sides


Check:
<span> 2 * 60 + 2 * 130 = 380 </span>

Genrish500 [490]

Answer: The volume of the composite figure is 420\text{ cm}^3.

Step-by-step explanation:

We know that the volume of a rectanbgular prism is given by :-

Volume = length x width x height

Given, for prism 1 , we have

length of 7 centimeters, width of 5 centimeters, and height of 8 centimeters

Volume of prism 1= (7)(5)(8)=280\text{ cm}^3

Given, for prism 2 , we have

length of 10 centimeters, width of 7 centimeters, and height of 4 centimeters.

Volume of prism 2= (10)(7)(4)=280\text{ cm}^3

Now , the volume of the composite figure = Volume of prism 1+ Volume of prism 2

=210\text{ cm}^3+210\text{ cm}^3=420\text{ cm}^3

Hence, the volume of the composite figure is 420\text{ cm}^3.
