It is: 8*13 = 104 square feet

The dimensions given are not that of a rectangle but are probably that of an isosceles trapezoid in which case it is:- Area = 0.5*(8+10)*2 = 18 square feet

The area of a 12-ft by 8-ft rectangle, expressed in metric units, is 8.919 square meters. (rounded)

let width= x length= 8ft+x area of rectangle= 345 area= l*b = 8+x*x=345 = 2x= 337 x=168.5 Length=176.5 Breadth=168.5 SORRY THE ANS IS WRONG.

Rectangle area = (rectangle width) x (rectangle height)

It is: 8*13 = 104 square feet

is equals to 2*19FT + 2*8FT

3 feet x 8 feet equals an area of 24 square feet.

To calculate the area of a rectangle you multiply the length by the width - 8 x 5 = 40, so the area is 40 square feet.

Area of rectangle = length x width Area_of_wall = 18ft x 8ft = 144 ft2
