Question

an umbrella is made by stitching 10 triangular pieces of cloth of two different colours each pieces measuring 20cm,50cm and 50 cm . How much cloth of each colour is required for the umbrella?​

Answer 1

Answer:

Area of each colour cloth = 1000√6

Step-by-step explanation:

Semi perimeter of a triangle = 20+50+50/2

= 60cm

then area = √s(s-a)(s-b)(s-c)

=√60×40×10×10

=200√6

There are 10 traingle pieces od two different colours

means 5 pieces of single colour cloth

Area of each colour cloth = 5×200√6

=1000√6
