What is the area of 8 and 12?

Summary: The area of a rectangle that is 8 inches wide and 12 inches long is 96 square inches.

How do you get the perimeter of a rectangle with the area and length?

Perimeter of a Rectangle

1. Remember the formula for perimeter and area of a rectangle. The area of a rectangle is a = length * width, while the perimeter is p = (2 * length) + (2 * width)
2. Substitute the known values into the area formula. 36 = 4 * w.
3. Substitute values for length and width into the perimeter formula.

What are side lengths of a rectangle?

A rectangle is composed of two sides: length (L) and width (W). The length of a rectangle is the longest side, whereas the width is the shortest side.

What is the area of a 12 by 8 rectangle?

Area of rectangle = 12 × 8 (inches) . Area of rectangle = 96 inch ² . Ans: Hence , the area of rectangle is 96 inch ².

How many square feet is a 8×12 room?

Multiply 12 x 8 = 96 square feet for each wall, then multiply 96 x 4 (since there are four walls with 96 square feet each)= 384 total square feet for the room.

How do you find the dimensions of a rectangle in units?

It is very simple my friend we have given that the Area A = 8 square units and The Perimeter P = 12 units. Find out the dimensions “it means the length L and the width W of the rectangle”. If (B-2)=0 , B =2 unit then L = (6-B) = (6–2) = 4 unit answer.

What is the area of a rectangle with a side 150mm?

Calculate the area of a rectangle with a length of 50 mm and a breadth of 3 cm. Give the answer in cm 2. Calculate the area of a square bathroom tile with a side of 150 mm. The area is therefore 22 500 mm 2 (or 225 cm 2 ). Calculate the length of a rectangle if its area is 450 cm 2 and its width is 150 mm.

What are the units of area and perimeter?

The perimeter is measured in units such as centimeters, meters, kilometers, inches, feet, yards, and miles. The area is measured in units units such as square centimeters (cm2) ( c m 2), square meters (m2) ( m 2), square kilometers (km2) ( k m 2) etc.

What is the formula to find the perimeter of a rectangle?

To find the perimeter of rectangle we add the lengths of its sides. Thus, the perimeter of a rectangle with the length of a a and the width of b b is P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b) P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b)
