Q. Find the perimeter of a rectangle with 20 cm and 12 cm, length and breadth respectively. We know that, Perimeter of a rectangle = 2(a + b) where, “a” is the length of the rectangle “b” is the breadth of the rectangle. ∴ P = 2(20+12) = 2(32) = 64 cm. Q. What is the perimeter of a rectangle 12 meters long with a 4-meter wide base?

To find the perimeter of a quadrant we need length of curved part which can be found using the formula 0.5 × π r and length of two straight lines which is equal to the radius as quadrant is combination of two radii and a curved part. Therefore the formula can be written as: The Perimeter of a Quadrant = 2 r + 0.5 × π r

The perimeter of a semicircle is the sum of half of the circumference of the circle and its diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius. Therefore, The perimeter of Semicircle = (1/2) π d + d. Or.

Let the length and breadth of the part be l and b Perimeter: 2 (l+b) = 80m or l + b =40m, l = Area: = .replace length l (40-b)b = 400 multiply (-1) throught the equation length of the park is 20m, l=40-b breadth =40-l=40-20=20 Length = 20m and breadth = 20m read more 0 Comments Sanjay Kumar Jha B.Tech, M.Tech, Delhi, 15 yrs teaching experience

Perimeter of a shape CCSS.Math: 3.MD.D.8 Google Classroom About Transcript To find the perimeter of a shape, you add up the lengths of all the sides. For a square or pentagon, it's even easier - you can multiply the length of one side by the number of sides to get the total perimeter. Created by Sal Khan. Questions Tips & Thanks

The formula for the perimeter of a rectangle is (width + height) x 2, as seen in the figure below: You need two measurements for a rectangle - width and length. Make sure both are in the same unit, or convert one of them as necessary.

Depending on what information you have available, there are many ways to calculate the length of a rectangle. If you have the area A and width w, its length w is determined as h = A/w. If you have the perimeter P and width w, its length can be found with h = P/2−w. If you have the diagonal d and width w, it's length is h = √ (d²−w²).
