0.5 * (10' * 12') = 0.5*120 sq feet = 60 square feet.
60 square ft.
10 feet
Area of a triangle in square feet = (one half of the length of the base in feet) times (height of the triangle in feet)
Area = 0.5*21*12.5 = 131.25 square feet
One square yard contains 9 square feet. So you obtain the answer by multiplying the number of square yards by 9. In this case the answer is 36 x 9 or 324 square feet.
60 square ft.
61.75 square feet. Multiply length by width - the result is the area in square feet.
Impossible to answer ! A room 5 feet by 15 feet will have the same area as one that's 3 feet by 25 feet !
10 feet
86.625 square feet.
28 The correct answer is 74 feet. (assuming the room is a rectangle). The Formulas you need to know are: Area is found by side x side. Then, side = Area/side, then, side = 322/23. This equals 14 feet for the other side of the room. Perimeter is the sum of all sides. 14+14+23+23= 74
One half yard equals one and one half feet because there are three feet in one yard, so half of three feet is one and one half feet.
Area of a triangle in square feet = (one half of the length of the base in feet) times (height of the triangle in feet)
Area = 0.5*21*12.5 = 131.25 square feet
The ratio is 2/3: One foot can be expressed as 2 half-feet and one and a half feet can be expressed at 3 half-feet.
One and one half feet
One square yard contains 9 square feet. So you obtain the answer by multiplying the number of square yards by 9. In this case the answer is 36 x 9 or 324 square feet.
