Question

*If the perpendicular sides of a right angled triangle are 8 cm and 12 cm long, then what is the area of ​​that right angled triangle?*

1️⃣ 96 sq.cm.
2️⃣ 48 sq.cm.
3️⃣ 64 sq.cm.
4️⃣ 72 sq.cm.​

Answer 1

Given:

One of the perpendicular side of the right angled triangle = 8 cm

The other perpendicular side of the right angled triangle = 12 cm

To find :

The area of the right angled triangle.

Solution:

The area of the right angled triangle = 1/2 × product of perpendicular sides

= 1/2 × 8 × 12

= 48 sq. cm

Therefore the area of the right angled triangle is 48 sq. cm and thus the correct option is 2.

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

If the perpendicular sides of a right angled triangle are 8 cm and 12 cm long, then what is the area of that right angled triangle

1. 96 sq.cm.

2. 48 sq.cm.

3. 64 sq.cm.

4. 72 sq.cm.

EVALUATION

Here it is given that the perpendicular sides of a right angled triangle are 8 cm and 12 cm long

Figure : Figure is referred to the attachment

Here in the figure :

Base = 12 cm

Height = 8 cm

Hence the required area of the right angled triangle

$\displaystyle \sf{ = \frac{1}{2} \times Base \times Height }$

$\displaystyle \sf{ = \frac{1}{2} \times 12 \times 8 \: \: \: sq.cm }$

$\displaystyle \sf{ = 6 \times 8 \: \: \: sq.cm }$

$\displaystyle \sf{ = 48 \: \: \: sq.cm }$

FINAL ANSWER

Hence the correct option is 2. 48 sq.cm
