area = base x height ÷ 2 ⇒ height = 2 x area ÷ base ⇒ height = 2 x 15 ÷ 3 = 10 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
Area = 1/2*(15+9)*7 = 84 square inches
180 sq in. ... that's (12 X 15)/2 equals 180.
225 sqin
Area = L*W = 15 * 2 = 30 square inches.
area = base x height ÷ 2 ⇒ height = 2 x area ÷ base ⇒ height = 2 x 15 ÷ 3 = 10 inches.

30 square inches. Area of triangle = (base x height) divided by 2.
formula for area of a trapezoidA= 1/2 *(a+b) *hA- areaa and b represent basesh- haightA=1/2 * (15+10) * 5A= 62.5 inand that's the final answer :)))
Height = Area/Base = 105/15 = 7 inches
If the radius is 2 then the diameter is 2*2 = 4 inches and the circumference is about 12.6 inches and not 15 inches
Surface area of rectangle: 15 times 8 = 120 square inches
