Question

A wire of length 2 m and 40 cm is cut into two equal pieces and bent to form a
square and an equilateral triangle. Find the length of the sides of the square and the
equilateral triangle​

Answer 1

Answer:

length of square is 30cm and equilateral triangle is 40cm.

Step-by-step explanation:

2m = 2×100=200cm

so, length of wire is 240cm

after cutting it the length of each piece is 240/2.

that is 120 cm.

perimeter of square is 4× side of square= 4×a

perimeter of equilateral triangle is 3× side of equilateral triangle=3×b

so , according to the question

4a= 120

a=120/4

a=30cm

and 3b=120

b= 120/3

b=40cm
