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...
Before going to know what is the diagonal of a rectangle formula, let us understand what is meant by the diagonal of a rectangle. The diagonal of a rectangle is a line segment that joins any two of its non-adjacent vertices. The formula for the diagonal of a rectangle gives the length ...
A rectangle is a closed 2-D shape, having 4 sides, 4 corners, and 4 right angles (90°). The opposite sides of a rectangle are equal and parallel. Since, a rectangle is a 2-D shape, it is characterized by two dimensions, length, and width. Length is the longer side of the recta...

This means, the area of the parallelogram would be equal to the area of the rectangle so formed. That is, $b \times h$ sq. units.TriangleWe can find the area of a triangle using the formula: $\frac{1}{2} \times \text{base} \times \text{height}$...
(4⋅6)/2=(24)/2=12.故选A.与矩形的高和底相等的三角形面积是矩形的面积的一半,这意味着底的一半,相同的高的三角形面积是矩形面积的四分之一,所以我们有(48)/4=12.故选A.Use the triangle area formula for triangles: A=(bh)/2, where A is the area, b is the base, and h is the...
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 knoww = 5andh = 3: Area = 5 × 3 =15 Area by Counting Squares We can also put the shape on a grid and count the number of ...
Shape:rectangle How to calculate the perimeter:2 x (L + W) How to calculate the area:L x W How to calculate the volume:Cuboid: W x H x D Shape:triangle How to calculate the perimeter:Side + side + side (a x b x c) How to calculate the area:(b x h) ÷ 2 ...
or, perimeter of the rectangle = 2l+2b, or, perimeter of the rectangle = 2(l+b), This is the formula for the perimeter of a rectangle.Answer and Explanation: Let x be the width of the rectangle, As given, the length of the rectangle is fixed...
Rectangle Rectangular. Rectangle A parallelogram with four right angles Common Curiosities How do you calculate the area of a parallelogram and a rectangle? Both use the base times height formula, but in a rectangle, any side can serve as the base due to the right angles. 11 What is a spec...
