Question

An umbrella is made by 16 triangular

pieces of cloth of two different designs, each

piece Measuring 20 cm, 50cm

and 50 cm. How much cloth of each design is

required for the umbrella?​

Answer 1

Answer:

1011.84 cm²

Step-by-step explanation:

sides of on triangular piece is 20 , 20, 50 cm

scalene triangle

Area = √(s-a)(s-b)(s-c)  where s = a+b+c  / 2

here s = (20+50+50)/2 = 120/2 = 60

so area of the umbrella = 16 * ( √(60-20)*(60-50)*(60-50)  )

                                       = 16 * √40*10*10

                                      = 16 * 10 * 2 * √10

                                     = 320* 3.162

                                    = 1011.84 cm²
