Find the area of this ISOSCELES triangleArea = ________ m²

Explanation
The area of an isosceles triangle can be found by multiplying the base length by the height and dividing the result by 2. In this case, since the base length and the height are not given, we cannot determine the area of the triangle. Therefore, the answer cannot be determined based on the information provided.

Find the area of this shape: Area = ________ cm²

Explanation
Divide the shape: Divide the L-shaped figure into two rectangles. One rectangle has dimensions 2 cm by 5 cm, and the other has dimensions 2 cm by 4 cm.
Calculate the area of each rectangle:
Area of the first rectangle: 2 cm * 5 cm = 10 cm²
Area of the second rectangle: 2 cm * 4 cm = 8 cm²Add the areas: Total area = 10 cm² + 8 cm² = 18 cm²

Find the area of this shape.Give your answer in mm² then in cm²Area = ________ mm² =________ cm²

Explanation
The given shape has an area of 30 mm². To convert this to cm², we divide by 100 since there are 100 mm in 1 cm. Therefore, the area in cm² is 0.3 cm². Additionally, 0.30 cm² is also a correct representation of the area in cm², as it is the same value but with an extra zero after the decimal point.

Work out the area of this trapezium. Area = ________ cm²

Explanation
The area of a trapezium is calculated using the formula:
Area = (1/2) * (sum of parallel sides) * height
In this case, the parallel sides are 2 cm and 4 cm, and the height is 3 cm.
Therefore, the area of the trapezium is:
Area = (1/2) * (2 cm + 4 cm) * 3 cm Area = (1/2) * 6 cm * 3 cm Area = 3 cm * 3 cm Area = 9 cm²

The area of the shape is given. Find the unknown length.missing length = ________ m

Explanation
The missing length is 4m. This is because all the given lengths are the same, indicating that the shape is a square. In a square, all sides are equal in length. Therefore, the missing length must also be 4m.

The area of this triangle is given. Work out the missing length.________ cm

Explanation
The given triangle is an equilateral triangle, which means all sides are equal. Since the area is given, we can use the formula for the area of an equilateral triangle, which is (sqrt(3)/4) * side^2. By plugging in the given area, we can solve for the missing length. In this case, the missing length is 16 cm, as all sides of the triangle are equal.
