Area of a right triangle

Find the area of the triangle by multiplying its base by its height and dividing the product by 2.

1. Multiply the base length {a} m by the height {b} m.
2. Divide the product by 2.
3. Write the answer in square metres (m²).

Calculation: ({a} × {b}) ÷ 2.

Formula: A = (b × h) ÷ 2.

Find the area of the triangle by multiplying its base by its height and dividing the product by 2.

1. Multiply the base length {a} m by the height {b} m.
2. Divide the product by 2.
3. Write the answer in square metres (m²).

Calculation: ({a} × {b}) ÷ 2.

Formula: A = (b × h) ÷ 2.

Calculate the areas of both right triangles using A = a · b / 2.

1. First triangle: A₁ = {a} · {b} / 2.
2. Second triangle: A₂ = {c} · {d} / 2.
3. Compare A₁ and A₂ and choose the greater area.

The area of a right triangle is half the product of its legs.

1. Multiply the lengths of the two legs: {a} · {b}.
2. Divide the product by 2.

Formula: A = ({a} · {b}) / 2. Give the answer in square centimetres (cm²).

The two perpendicular sides of a right triangle may be used as its base and height.

1. Find the lengths of the two perpendicular sides in the diagram.
2. Multiply them.
3. Divide the product by 2 because two such triangles would form a rectangle.

Formula: A = (a × b) ÷ 2.

Calculate the areas of both right triangles using A = a · b / 2.

1. First triangle: A₁ = {a} · {b} / 2.
2. Second triangle: A₂ = {c} · {d} / 2.
3. Compare A₁ and A₂ and choose the greater area.

The area of a right triangle is half the product of its legs.

1. Multiply the lengths of the two legs: {a} · {b}.
2. Divide the product by 2.

Formula: A = ({a} · {b}) / 2. Give the answer in square centimetres (cm²).

The area of a right triangle is given by A = a · b / 2. When the area and one leg are known, rearrange the formula to find the other leg.

1. Multiply the area by 2: 2 · {a}.
2. Divide the result by the known leg length {b}.

Formula: unknown leg = 2 · {a} / {b}. Give the answer in centimetres.

The area of a right triangle is calculated using A = a · b / 2.

1. Multiply the area by 2: 2 · {s}.
2. Divide the result by the known leg {b}.

Other leg = 2 · {s} / {b}. Give the answer in centimetres.
