Question

The perimeter of the triangle is 70cm the area is A cm^2

Answer 1

PERIMETER = 70 CM

LET THE SIDE BE X

X + X + X = 70

3X = 70

X = 70 ÷ 3 = 23.3 cm

AREA =

$\sqrt{} {70(70 - 23.3) \times (70 - 23.3)} \times (70 - 23.3)$

$\sqrt{70 \times 46.7 \times 46.7 \times 46.7}$

AREA = 2670 cm

${}^{area \: = 2670cm2}$
