Answer: 24.25cm^{2}

Step-by-step explanation:

The formula for calculating the area of a triangle given the apothem and perimeter is

Area = \frac{1}{2} x apothem x perimeter

apothem = 2.16

perimeter = 22.45

substituting into the formula , we have

Area = \frac{1}{2} x 2.16 x 22.45

Area = 24.246cm^{2}

Area≈ 24.25cm^{2}

Use inverse operations to love each equation--
Dominik [7]

a.) you start with 19=h/3-8 so you add 8 to both sides then you simplify 19+8 to 27 so the equation then becomes 27=h/3 from there you multiply each side by 3 so its 27*3=h then you simplify 27*3 which leaves you with 81=h u then switch it around and your final answer h=81

b.) you start with 0.6x +0.8=1.4 first you subtract 0.8 from both sides so the equation is 0.6x=1.4-0.8 then you simplify 1.4-0.8/ so it then becomes 0.6x=0.6 u then divide both sides by 0.6 so the equation is now x=0.6/0.6 you then simplify 0.6/0.6 so you are left with x=1
