Area is 36cm2
The area of a triangle is half the base times height.
If it is a rectangle then area = base × height = 7cm × 12 cm = 84 cm². If it is a triangle (more likely given the terminology used) then area = ½ base × height = ½ × 7 cm × 12 cm = 42 cm²
volume prism = area base × height = 32 cm² × 7 cm = 224 cm³
The area of triangle is : 48.96
Area of triangle = 0.5*base*height = 0.5*14.4*6.8 = 48.96 sq cm.
Area = Base*Height so Base = Area/Height = 720/15 = 48 cm
The area of a triangle is half the base times height.
Area = Base*Height (in consistent units). So Base = Area/Height = 144 cm2/700 cm = 0.2057 cm.
If it is a rectangle then area = base × height = 7cm × 12 cm = 84 cm². If it is a triangle (more likely given the terminology used) then area = ½ base × height = ½ × 7 cm × 12 cm = 42 cm²
The formula for the area of a triangle is ½ x base x height. We are given that the base = 13 cm and the height = 8 cm. Thus, the area of the triangle = ½ x 13 cm x 8 cm = 52 cm.
Multiply the base area by the height, and you have the volume.
volume prism = area base × height = 32 cm² × 7 cm = 224 cm³
The area of triangle is : 48.96
Area = 1/2*base*height = 3.5 x 2.1 = 7.35 sq cm
Base = Area/Height = 7886.2/95.7 = 82.405 cm (to 3 dp)
Area of triangle = 0.5*base*height = 0.5*14.4*6.8 = 48.96 sq cm.
halve the base (5.5) x height = 132cm2
