What is the lateral surface area of the geometric rectangle?
The surface area is L*B where L is the length of the rectangle and B is the breadth.
What area of this rectangle?
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.
What area is 14 square feet?
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
The side of a square equals the width of a rectangle the length of the rectangle is 6 meters longer than its width the sum of the areas of the square and the rectangle is 176 sq meters?
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.
What is the formula for Area a rectangle?
the formula for a rectangle is L x W where L is length and W is width.
The perimeter of a rectangle is 18 feet and the area of the rectangle is 14 feet What is the length of the rectangle?
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.
What is the formula for finding the area of a rectangle?
Area of rectangle is l x b. Where l is length and b is breath of the rectangle.
What the formula for finding the area of a rectangle?
Area of a rectangle: a = l * w
Which is the area of a rectangle with a l?
Area of a rectangle in square units = length*width

What is the formula for Area a rectangle?
the formula for a rectangle is L x W where L is length and W is width.
Rectangle has a perimeter of 36ft and is 4ft wide what is the area?
Perimeter = 2*(Length + Width) So 36 = 2*(L+4) => 18=L+4 => L = 14 ft So area = Length * Width = 14*4 = 56 sq ft
What are the dimensions of a rectangle if the area is 14 square inches?
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.
What kind of operation do you need to calculate the are of a rectangle?
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.
