B。解析:文章中明确提到“The perimeter of a rectangle is the total length of all its sides. To find the perimeter of a rectangle, we add up the lengths of all four sides. Since opposite sides of a rectangle are equal, the perimeter can be calculated as follows: P = 2(length + width...
Area formulas give us the sizes of everything from baking pans to house plans. Knowing how to use them is key. GRADIENT BACKGROUND/Shutterstock Key Takeaways The common formula for the area of a triangle is A = b × h / 2, where b is the base and h is the height. Other methods...
What is the formula for the area of a circle? What is the center of the circle 4x^2 + 4y^2 + 24y - 4x - 35 = 0? What is the center of the circle (x - 3)^2 + (y + 5)^2 = 36? Given f(x) = 3x + 5 and g(x) = 5 - x, find: a) f circle g b) g circle...
So, the unit of area of a rectangle is ‘square units’. Let’s understand how to find the area of a rectangle using unit squares.Example 1: Divide the rectangle ABCD into unit squares, as shown. The area of a rectangle ABCD is the total number of unit squares contained within it....

Area of Simple ShapesThere are special formulas for certain shapes:Example: What is the area of this rectangle? The formula is: Area = w × h w = width h = height The width is 5, and the height is 3, so we know w = 5 and h = 3: Area = 5 × 3 = 15Learn more at Area ...
You multiply the two lengths to get the area. In this case you have to convert yards to feet (or feet to yards) first. So you get 1,575 square yards. This answer is: Add your answer: Earn +20pts Q:What is the formula to find the surfa...
Hint:Here we have to find the formula for the surface area of a box. Firstly we will form the diagram of the box then we will level all the dimensions of it. As we know a box is either in the shape of a rectangle or a square so we will form a common formula to find ...
