Black and White coloured triangular sheets are used to make a toy as shown in figure find the total area of black and white colour sheet used for making the toy
Area of one black sheet =s=6+6+4÷2=8 3.31 of one black sheet for 2 black sheet =2×3.31=6.62 similarly for one white sheet =3.31 for 2 white sheet =2×3.31=6.62

Area of one black sheet =s=6+6+4÷2=83.31 of one black sheet
for 2 black sheet =2×3.31=6.62
similarly for one white sheet =3.31
for 2 white sheet =2×3.31=6.62

Answer:
Step-by-step explanation:
Sides of white triangle
a = 6
b = 6
c = 4
Area of triangle =![A=\sqrt{s(s-a)(s-b)(s-c)} A=\sqrt{s(s-a)(s-b)(s-c)}](https://tex.z-dn.net/?f=A%3D%5Csqrt%7Bs%28s-a%29%28s-b%29%28s-c%29%7D)
Substitute the values
Since the dimensions of all the triangles are equal
So, Area of 4 triangles =![11.31 \times 4 = 45.24 cm^2 11.31 \times 4 = 45.24 cm^2](https://tex.z-dn.net/?f=11.31%20%5Ctimes%204%20%3D%2045.24%20cm%5E2)
Hence the total area of black and white colour sheet used for making the toy is![45.24 cm^2 45.24 cm^2](https://tex.z-dn.net/?f=45.24%20cm%5E2)
