Question

The area of a triangle whose base is 12 cm and the Height twice the base, is
A) 144sq.cm B) 288 sq. cm C) 289 sq. cm D) Cannot be determined

Answer 1

Hey there ‼
_____________________

Base of ∆ = 12 cm

Height of ∆ = 2 × Base of ∆
= 2 × 12
= 24 cm

Area of ∆ = 1/2 × Base × Height
= 1/2 × 12 × 24
= 12 × 12
= 144 cm²

ANSWER :- A) 144 sq. cm

Answer 2

In context to questions asked,

We have to determine the value of area of triangle.

As per questions,

Base of triangle = 12 cm

Height of triangle = twice as the base $=2 \times 12 = 24\:cm$

As we know that,

Area of triangle can be determined by using the formula,

$\frac{1}{2} \times \: b \times h$

So, for determining the area of triangle we will put the value given in the questions.

Thus we will get,

$Area = \frac{1}{2} \times 12 \times 24 \\ = > Area = 6\times 24 = 144\:cm^2$

Hence value of base of triangle will be 144 Sq. cm
