Find the area of a triangle whose sides are 40cm,24cm and 32cm using heron's formula

Step-by-step explanation:

a = 40 cm

b = 24 cm

c = 32 cm

a + b + c  = 40 + 24 +32 = 96

S = a +b + c /2  = 96/2 = 48 cm

S - a = 48 - 40 = 8 cm

S - b = 48 - 24 = 24 cm

S - c = 48 - 32  =16 cm

Area = √S*(S-a) * (S-b) * (S-c)

        = √ 48 * 8 * 24 * 16   = √ 6 * 8 * 8 * 6 * 2 * 2 * 4 * 4

          = 6 * 8 * 2 * 4 =  384 Sq. cm

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
