60 square ft.
0.5 * (10' * 12') = 0.5*120 sq feet = 60 square feet.
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
1 and 1 half 3 one yard then the 1 and one half feet is one half of a yard so 1 and 1 half feet.
61.75 square feet. Multiply length by width - the result is the area in square feet.
0.5 * (10' * 12') = 0.5*120 sq feet = 60 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.
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.
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
Area of a triangle in square feet = (one half of the length of the base in feet) times (height of the triangle in 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
Area = 0.5*21*12.5 = 131.25 square feet
1 and 1 half 3 one yard then the 1 and one half feet is one half of a yard so 1 and 1 half feet.
