cm²

Answer:_______________

1)

The figure below is not drawn to scale.
Find the area of the triangle ABC.

Answer: 516 cm²

SOLUTION 1 :

Step 1: Length of AC → 25 cm + 18 cm = 43 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 24 cm x 43 cm = 516 cm²

2)

The figure below is not drawn to scale.
Find the area of the triangle ABC.

Answer: 450 cm²

SOLUTION 1 :

Step 1: Length of BC → 15 cm + 30 cm = 45 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 45 cm x 20 cm = 450 cm²

3)

The figure below is not drawn to scale.
Find the area of the triangle ABC.

Answer: 304 cm²

SOLUTION 1 :

Step 1: Length of AC → 29 cm + 9 cm = 38 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 16 cm x 38 cm = 304 cm²

4)

The figure below is not drawn to scale.
Find the area of the triangle ABC.

Answer: 490 cm²

SOLUTION 1 :

Step 1: Length of AB → 15 cm + 34 cm = 49 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 49 cm x 20 cm = 490 cm²

5)

The figure below is not drawn to scale.
Find the area of the triangle ABC.

Answer: 296 cm²

SOLUTION 1 :

Step 1: Length of BC → 12 cm + 25 cm = 37 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 37 cm x 16 cm = 296 cm²

6)

The figure below is not drawn to scale.
Find the area of the triangle ABC.

Answer: 684 cm²

SOLUTION 1 :

Step 1: Length of AB → 18 cm + 39 cm = 57 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 57 cm x 24 cm = 684 cm²

7)

The figure below is not drawn to scale.
Find the area of the triangle ABC.

Answer: 288 cm²

SOLUTION 1 :

Step 1: Length of AB → 9 cm + 27 cm = 36 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 36 cm x 16 cm = 288 cm²

8)

The figure below is not drawn to scale.
Find the area of the triangle ABC.

Answer: 180 cm²

SOLUTION 1 :

Step 1: Length of AC → 21 cm + 9 cm = 30 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 12 cm x 30 cm = 180 cm²

9)

The figure below is not drawn to scale.
Find the area of the triangle ABC.

Answer: 92 cm²

SOLUTION 1 :

Step 1: Length of BC → 6 cm + 17 cm = 23 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 23 cm x 8 cm = 92 cm²

10)

The figure below is not drawn to scale.
Find the area of the triangle ABC.

Answer: 96 cm²

SOLUTION 1 :

Step 1: Length of AC → 18 cm + 6 cm = 24 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 8 cm x 24 cm = 96 cm²
