Question

Construct a triangle with base 4.5cm and perimeter as 11.7cm????

Answer 1

first we draw the base BC of 4.5 cm then by ruler measure 11.7 and draw a arc then join the arc it is a triangle

Answer 2

AB =  4.5 cm

BC =  3.6 cm

AC =  3.6 cm

Step-by-step explanation:

given data

base = 4.5 cm

perimeter =  11.7 cm

solution

first we draw a line AB of length = 4.5 cm

and we have given perimeter =  11.7 cm

so we consider triangle is ABC

so perimeter is sum of all three side

perimeter = AB + BC+ AC   .............1

11.7 cm  = 4.5  + BC+ AC  

BC+ AC  = 7.2 cm

we take BC =  AC

so BC = AC =  $\frac{7.2}{2}$ =  3.6 cm

now we draw a arc from point A and B of 33.6

then then join the arc where it cut each other at point C

so as it is triangle
