...equal to n. Am B n A -=- = a. §324. -=- = b. §325. - = aXb. §269. B u U u U QED 327. COROLLARY. — The area of a rectangle is equal to the product of the measures of the base and altitude times the unit of measure. A Since — = a X b, A = (a X 6) U, ie,...

...This is a familiar fact in the case of rectangles ; the common form of statement for this case being that the area of a rectangle is equal to the product of its length and width. From any rhomboid or rhombus, a rectangle of the same dimensions can be constructed,...

...following : If the unit of surface is a square whose side is the linear unit, the number which expresses the area of a rectangle is equal to the product of the numbers which express the lengths of its sides. An interpretation of this form is always understood...

...the length of the rectangle, and x — 5.'= the number of feet in the width of the rectangle. Since the area of a rectangle is equal to the product of the number of units of length in the length and width of the rectangle, (x + 6) (x — 5) = the area of...

...following : If the unit of surface is a square whose side is the linear unit, the number which expresses the area of a rectangle is equal to the product of the numbers which express the lengths of its sides. PLANE GEOMETRY. — BOOK IV. 307. Cor. The area of...

...-LX J. = ba, answer. Using A for area, the result may be written as follows : RELATION I. Abstractly, the area of a rectangle is equal to the product of the base and altitude. EXAMPLES. 1. Find the area of a wall 20 ft. long and 7£ ft. high. Solution: (1) A =...

...square units are there in a rectangle 10 units long and 7 units wide ? 3. The number of square units in the area of a rectangle is equal to the product of the numbers of the like units in the lenyili and width. What is the area of a rectangle 6 in. long and...

...RECTANGLE. 64. The number of square units in a rectangle is called its area. From the above it is evident that the area of a rectangle is equal to the product of its length and width. The length and width are called the two dimensions of the rectangle. 65. The...
