Area of a right angled triangle How to work out area Area of a quadrilateral Area of a hexagon Area of a pentagon Area of a rectangle examples Example 1: Finding area given the length and width Find the area of the rectangle below: ...
The length of thediagonalof a rectangle can be calculated if the length and width is known. Since the diagonal of a rectangle forms a right-angled triangle with its sides, the diagonal becomes the hypotenuse and its value can be calculated using the Pythagoras theorem. For example, if the l...
in geometry, "quadrilateral plane figure having all its angles right and all its opposite sides equal," 1570s, from Frenchrectangle(16c.), fromrect-, combining form of Latinrectus"right" (from PIE root*reg-"move in a straight line," with derivatives meaning "to direct in a straight line...
说明/解释:这个表达强调了矩形是一种四边形,且所有角都是直角。 第二条:four-sided figure with equal opposite sides 说明/解释:这个表达突出了矩形有四条边,且对边相等的特性。 第三条:right-angled quadrilateral 说明/解释:这个表达简洁明了,直接指出矩形是一个有四个直...
Since, a rectangle has parallel sides, we can also call it a right-angled parallelogram. A parallelogram is a quadrilateral whose opposite sides are equal and parallel. Rectangles are special case of paralleograms. What is a Diagonal of a Rectangle? The line segments that join the opposite co...

noun A four-sided plane figure with four right angles. from The Century Dictionary. noun A right-angled triangle. Rectangular; right-angled. noun A quadrilateral plane figure having all its angles right angles and its opposite sides consequently equal. noun The product of two lengths. noun A ...
A rectangle is a2-dimensional shape/polygonwith four sides, four vertices, and fourright angles.The two opposite sides in the rectangle are equal and parallel to each other. What is the area of a rectangle? It is the space covered by theshapeor the space within the perimeter of the rectan...
The area of a rectangle can be calculated if the perimeter and one of its sides is given. With the help of the perimeter, we can find the unknown side and then calculate the area using the same formula, Area of rectangle = Length × Width. Let us understand this with the help of an...
Oblong is a shape elongated in one direction. Rectangle is a 4-sided polygon with opposite sides equal and all angles 90 degrees. Both are quadrilaterals, but all rectangles can be oblongs, not all oblongs are rectangles.
