What shape is a rectangle?
An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides. A rectangle has two dimensions—length and width—because it is a two-dimensional form.
What is the formula for area of rectangles?
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle as Area = length x width
Length of the sheep pen =80 ft
bought fencing = 180 ft
One side of rectangular sheep pen is covered with barn which is equaling the width
perimeter of rectangular sheep pen = 2(length +width)
length need to covered is 2 Length+ width
180 =2 length+width
180 = 2 x80 +width
180-160= width
20= width
Area of rectangle = 80 x 20
=1600 square feet
