A triangle has an area of 144 sq inches and its base is 2 ft long What is the altitude of the triangle?
First convert the base to the same kind of units you have defined the area in (but linear); 24 inches. The area of a triangle is half of the base times the height .12 (half the base) times what is 144?12, the height (altitude) of the triangle is 12 inches (one foot).
A triangle is dilated with a scale factor of 2 If the area of the original triangle is 9 square inches what is the area of the image in square inches?
Area is proportional to the square of the linear dimensions. If the linear dimensions are doubled, the area is increased by a factor of 22 = 4. The new area is 9 x 4 = 36 square inches.
The legs of a right triangle are 12 and 16 inches long respectively What is the area of the triangle?
Lets work it out:- If the legs are 12 and 16 inches, then a rectangle of that size would be 192 square inches in area. As the the diagonal of the rectangle makes two equal triangles (of legs 12 and 16 inches), the area of one of these is half the area of the triangle - 192/2 = 96 square inches.

Area = 0.5*Base*Altitude = 0.5*20*5 = 50 square inches.
The legs of a right triangle are 8 and 28 inches long what is the area?
The formula for the area (A) of any triangle is A = 1/2base x altitude (or height). The area of a right angled triangle with base = 8 and altitude = 28 is therefore :- A = 1/2 x 8 x 28 = 112 sq inches
