Question

please find answer for this question

Answer 1

let one unit be x
then the sides are 2x, 3x, 5x, 7x
a/q
2x+ 3x+5x +7x = 340m
17x = 340m
x = 340m / 17
x = 20m
therefore, sides are 40, 60, 100 ,140

Answer 2

let x be the common multiple.
$340 = 2x + 3x + 5x + 7x \\ 340 = 17x \\ x = \frac{340}{17} \\ x = 20$
$2x \\ 2 \times 20 = 40 \\ 3x \\ 3 \times 20 = 60 \\ 5x \\ 5 \times 20 = 100 \\ 7x \\ 7 \times 20 = 140$

$s = \frac{a + b + c + d}{2} \\ \frac{40 + 60 + 100 + 140}{2} \\ \frac{340}{2} \\ s = 170$
$\sqrt{(s - a)(s - b)(s - c)(s - d)} \\ \sqrt{170 - 40 \times 170 - 60 \times 170 - 100 \times 170 - 140} \\ \sqrt{130 \times 110 \times 70 \times 30} \\ \sqrt{30030000} \\ 5479.96$
