Question

Pls help its number 16 or the highlighted in pink

Answer 1

Explanation:

let xbe side of A.

let x=3

then perimeter=3×3= 9 m

area=1/2×3×√(3²-(3/2)²=1/2×3×3√3/2=9√3/4≈3.879≈3.9 m²

side of triangle B=27/3=9 m

area of triangle=1/2×9×√(9²-(9/2)²=1/2×9×9√3/2=81√3/4≈35.07 ≈35.1 m²

or side of B=3×3=3×side of A

area of triangle B=3²×area of A=9×3.9=35.1 m²
