Answer:_______________

1)

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

Answer: 4992 cm²

SOLUTION 1 :

Step 1: Length of AC → 120 cm + 36 cm = 156 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 64 cm x 156 cm = 4992 cm²

2)

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

Answer: 868 cm²

SOLUTION 1 :

Step 1: Length of AB → 21 cm + 41 cm = 62 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 62 cm x 28 cm = 868 cm²

3)

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

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: 12024 cm²

SOLUTION 1 :

Step 1: Length of BC → 81 cm + 86 cm = 167 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 167 cm x 144 cm = 12024 cm²

6)

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

Answer: 88 cm²

SOLUTION 1 :

Step 1: Length of AB → 6 cm + 16 cm = 22 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 22 cm x 8 cm = 88 cm²

7)

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

Answer: 304 cm²

SOLUTION 1 :

Step 1: Length of AB → 12 cm + 26 cm = 38 cm

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

8)

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

Answer: 26 cm²

SOLUTION 1 :

Step 1: Length of AC → 10 cm + 3 cm = 13 cm

Step 2: Area of triangle ABC → $\frac{1}{2}$ x 4 cm x 13 cm = 26 cm²

9)

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

10)

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
