Question

find area of a equilateral triangle with side 10 cm using heron's formula

Answer 1

Step-by-step explanation:

what is herons formula

Answer 2

Answer:

the sum is we should find the area of the triangle by herons formula

Step-by-step explanation:The side of the triangle is 10 cm

so by herons formula= √s{s×a}{s×b}{s×c}

perimeter=10×3=30cm{sum of all angles}

s=a+b+c÷2

s=30÷2=15

so s=15

area of the triangle=√15{15×10}{15×10}{15×10}

√15×150×150×150

√2250×22500

√2250×150

47×150=7050

a=7050÷2=3525

a=3525cm²
