Answer 1

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

Question

• The length of the side of triangular park are 90cm,70cm,40cm find its area?

Answer

• Area = 1344cm²

Given

• Length of Sides are 90cm,70cm,40cm

To Calculate

• Area __?

Step by Step Explanation

Length of Sides are 90cm,70cm,40cm

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

➥ (90+70+40)/2

➥ 200/2

➥ 100

☆ Using Heron's formula

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

➥ √100(100-90)(100-70)(100-40)

➥ √100×10×30×60

➥ √2×2×5×5×2×5×2×3×5×2×2×3×5

➥2×5×2×5×3×2 √5

➥ 600√5

➥ 600×2.24

➥ 1344cm²
