Question

Danny is installing a fence around his rectangular yard. His yard is 20 feet long by 45 feet wide. If the fencing he picked out costs 25$ per foot, how much money will Danny spend on the fence?

Answer 1

Find the perimeter of the yard ( the distance around the yard).

A rectangle has two sides of each dimension.

The perimeter is 20 + 20 + 45 + 45 = 130 feet.

Now multiply the total feet by the cost per foot:

130 feet x 25 per foot = $3,250 total.

Answer 2

Danny needs to spend on his yard $3250 to fencing.

What is a rectangle?

The rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Length of fence = Perimeter of his yard(rectangle)

Perimeter of rectangle = 2( length + width).

Perimeter of fence =2 ( 20 + 45 )

The perimeter of fence =130 foot.

Now

Cost = $25 per foot

So,

Cost of 130 feet at the rate of  $25 per foot

⇒ 130 × 25 = $3250

Hence, Danny needs to spend on his yard $3250 to fencing.
