what are the perimeter and area of a rectangle with a length of 20 in. and a width of 15 in.?

Answer 1

The perimeter of a rectangle is the sum of all its sides. Therefore, the perimeter of the rectangle with a length of 20 in. and a width of 15 in. is:

Perimeter = 2 × (Length + Width)
Perimeter = 2 × (20 in. + 15 in.)
Perimeter = 2 × 35 in.
Perimeter = 70 in.

The area of a rectangle is calculated by multiplying its length by its width. Therefore, the area of the rectangle is:

Area = Length × Width
Area = 20 in. × 15 in.
Area = 300 sq. in.

So, the perimeter of this rectangle is 70 inches and the area is 300 square inches.
