What is its area? Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area. In this example, 14 ÷ 4 = 3.5.
To find the perimeter of a rectangle, add the lengths of the rectangle’s four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.
Answer: The area of a square is equal to the square of the length of its side and the perimeter of the square is 4 times the length of its side. Let the length of the side of a square be ‘a’ units.
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
Thus, the area of the square is 144 cm2.
The surface area of a 7 cm cube will be 294 cm2 .
Answer: The perimeter of rectangle is 48 cm.
= 5×3 = 15cm^2.
Area = (24×12)/2 = 144 sq. cm.
R2 (radius squared) means radius × radius. Therefore a circle with a radius of 5cm has an area of: 3.142 × 5 × 5 = 78.55cm2.
The area of a circle is equal to Pi π times the radius r squared. Substitute in the value of the radius r=8 into the formula for the area of a circle. Pi π is approximately equal to 3.14 .
Area of a Square Formula
Now, let us use this formula to find the area of a square of side 7 cm. We know that the area of a square = Side × Side. Substituting the length of side 7 cm, 7 × 7 = 49. Therefore, the area of the given square is 49 cm2.
So,Perimeter of rectangle=22Cm.
We know that the perimeter of the quadrilateral = the sum of all the sides of the quadrilateral ABCD = (AB + BC + CD + DA). We have all the values for the sides, so we get the perimeter as, = (8 + 5 + 13 + 10) cm = 36 cm.
A rectangle has 4 sides: 2 of them will be the length (8cm) and 2 of them the width (3cm). To get the perimeter, you add up 2 of the length and 2 of the width: 2 x 8 + 2 x 3. The answer therefore is 22cm (don’t forget the units!) The area of the rectangle is worked out by mulitplying the length by the width: 8 x 3.
Find the area and perimeter of a rectangle of length 10cm and breadth 4cm. ❄️ Therefore, the area and perimeter of a rectangle whose length and breadth are 10cm and 4cm are 28cm and 40cm² respectively.
the area of ractangle is 21 cm square.
Area is always expressed as square units (units2). This is because it is two-dimensional (length and height).
The perimeter of a shape is the total measurement of all the edges of a shape e.g. a triangle has three edges, so its perimeter is the total of those three edges added together. … The perimeter of a rectangle can be calculated by adding the length and width together and doubling it.
The perimeter of a shape is the total distance around the shape, or the lengths of its sides added together. Perimeter (P) is measured in units such as millimetres (mm), centimetres (cm) and metres (m).
Multiply the length by the width and you’ll have the square feet. Here’s a basic formula you can follow: Length (in feet) x width (in feet) = area in sq. ft.
