Answer 1

$\bf\underline{\underline{\red{SOLUTION:-}}}$

Question

• The sides of traingle 8cm,11cm,13cm what is it area?

Answer

• Area of triangle = 8√30 cm²

Given

• Sides are 8cm ,11cm,13cm

To Calculate

• Area__?

Explanation

Semi perimeter = (a+b+c)/2

➩ (8+11+13)/2

➩ 32/2

➩16

☆ Using Heron's formula ☆

$Area \: of \: triangle = \sqrt{s(s - a)(s - b)(s - c)}$

putting values,

$= \sqrt{16(16 - 8)(16 - 11)(16 - 13)}$

$= \sqrt{16 \times 8 \times 5 \times 3}$

$= 4\sqrt{8 \times 5 \times 3}$

$= 4\sqrt{4 \times 2 \times 5 \times3}$

$= 8\sqrt{2 \times 5 \times 3}$

$= 8\sqrt{30} \: cm ^{2}$

$\bf\underline{\underline{\red{HENCE:-}}}$

• Area of triangle = 8√30 cm²
