The surface area is L*B where L is the length of the rectangle and B is the breadth.

In order to find the area of a rectangle, you must follow the formula A= l x w where A is area, l is length, and w is width.

Any rectangle with a length and width that multiply together to equal 14. L=14 W=1, or L=7 W=2, or L=10, w=1.4 or L=5 w=2.8 etc

Let L be the length of the rectangle. Since the length of the side of the square is the same as the width of the rectangle and the width of the rectangle is its length minus 6, the length of the side of the square is (L-6) and the area is (L-6)2. Since the width of the rectangle is its length minus 6, its area is L(L-6). Here is some of the work: 176 = (L-6)2 + L(L-6) 176 = (L-6)(L-6) + L(L-6) 176 = L2 - 6L - 6L + 36 + L2 - 6L 176 = 2L2 - 18L + 36 140 = 2L2 - 18L 70 = L2 - 9L 70/L = L - 9 (9L + 70)/L = L L = (9L+70)/L L2 = (9L+70) L = sqrt(9L+70) According to WolframAlpha (www.wolframalpha.com), L=14. (But don't say L; use x). The length of the side of the square is 8 m, which is also the width of the rectangle; the length of the rectangle is 14 m; the area of the square is 64 m2; and the area of the rectangle is 112 m2.

First of all to correct . The area is NOT 14 feet , that is a liner measurement, but 14 sq.ft. (square feet) #Hence A = lb = 14 sq.fr. P = 2( l + b) = 18ft. b = 14/l & l + b = 9 Substitute (14/l) + l = 9 Multiply though by 'l' 14 + l^2 = 9l l^2 - 9l + 14 = 0 Factor ( l - 7)(l - 2) = 0 Hence l = 7 ft. and l = 2ft Common sense dictates that the length is 7 ft.

the formula for a rectangle is L x W where L is length and W is width.

Perimeter = 2*(Length + Width) So 36 = 2*(L+4) => 18=L+4 => L = 14 ft So area = Length * Width = 14*4 = 56 sq ft

area is calculated by doing length (l) times width (w). The formula is: A = l x w. if you substitute 14 for A, you get 14 = l x w. Now find the factors of 14, which are 7 and 2. put them in for l and w, and you get 14 = 7 x 2. To check your answer, simply do 7 x 2 and see if it equals 14.

MULTIPLICATION area for a rectangle is A = L * W * H where, A = area of rectangle L = Length of rectangle W = width of rectangle H = height of rectangle The dimensions of a rectangle (L, W, and H) are interchangeable because they are being multiplied together and hence each side of the rectangle can be arbitrarily assigned to a dimension.
