Answer:

Area= 156ft^2

Step-by-step explanation:

Given

Two Rectangles;

Rectangle_1 = 12ft\ by\ 7ft

Rectangle_2 = 12ft\ by\ 6ft

Required

Determine the area of the shape

The area of the shape would be;

Area = Area\ of\ Rectangle\ 1 + Area\ of\ Rectangle\ 2

Area of rectangle is calculated as:

Area = Length * Width

For the first rectangle:

Area = 12ft * 7ft

Area = 84ft^2

For the second:

Area = 12ft * 6ft

Area = 72ft^2

So:

Area of the shape is

Area= 84ft^2 + 72ft^2

Area= 156ft^2

Harman [31]

Answer:

The length of each smaller piece, l=L/n inches

Step-by-step explanation:

This can be expressed as;

Total length=Length per piece×number of pieces

where;

The total length=L

length per piece=l

number of pieces=n

Substituting in the equation;

L=l×n

To get the length of each smaller piece;

l=L/n inches

solving;

l=30.75/3=10.25 inches

andrey2020 [161]

Answer:

88 ft

Step-by-step explanation:  Start with the formula for the area of a rectangle:

A = L*W, where L is the length and W is the width.

Here, the width is W = 24 ft, and the area i s 480 ft^2.  Thus,

A = 480 ft^2 = L (24ft), which yields L = (480/24) ft = 20 ft.

The length of the fencing required is actually the perimeter of the yard, which is P = 2L + 2W.

Substituting 20 ft for L and 24 ft for W, we get:

P = perimeter of yard = amount of fending needed:

P = 2(20 ft) + 2(24 ft) = 88 ft

Ken would need 88 ft of fencing to enclose his entire yard.
