Answer 1

Answer:

$120cm \: square$

Answer 2

Step-by-step explanation:

Sides of Triangle =16cm,20cm & 24cm respectively.

To find

Area of Triangle

Solution

step by step explanation

We have given 3 sides of Triangle so we use Heron's formula to find out the area.

The given triangle is a scalene Triangle.

S=a+b+c/2

S=16+20+24/2

S=60/2=30

S=30cm

Now area of Triangle=√S(S-a)(S-b)(S-c)

Area=√30(30-16)(30-20)(30-24)

Area=√30×14×10×6

Area=√2×3×5×2×7×2×5×2×3

Area=√2×2×2×2×3×3×5×5×7

Area=2×2×3×5√7

Area=60√7cm²
