A rectangle does not have a slant height. It is therefore likely that the shape is something other than a rectangle. What it is, is unknown and so the question cannot be answered.
Area of a rectangle = length X height = 3*13 = 39 square feet.
Using Pythagoras its base works out as 36 and so 36*15 = 540 square units
156 It is impossible to calculate the area of a rectangle from its perimeter if no other dimension is known. The area of a rectangle is the product of its length and width, and the perimeter is twice the sum of its length and width.
The size of the rectangle could be 13 feet by 3 feet
A = 540 units squared.
80 feet
It's greatest possible perimeter: 1+39+1+39 = 80 feet
To find the area of a rectangle with sides that are 39 and 16, you would multiply the two numbers (length times width) to get your answer. 39 x 16 = 624
To find the area of a rectangle (or the product of its length and width), you can simply multiply the length by the width. In this case: Area = Length × Width Area=Length×Width Area = 39 inches × 47 inches Area=39inches×47inches Area = 1833 square inches Area=1833square inches So, the area of a rectangle with dimensions 39 inches by 47 inches is 1833 1833 square inches.
Area=(1/2)(base times height). This is written as A=bh/2. The base is 39 inches and the height is 15 inches, so: A=(39x15)/2=585/2=292.5 square inches
39 cm
Area of a triangle = 1/2 * Base * Height = 1/2 * 12 * 6.5 = 39 cm2
