Question

A square and an equilateral triangle have a side in common. If side of triangle is 4 cm long, find the perimeter of figure formed .

Answer 1

Answer:

Perimeter of Figure formed = 4 + 4 = 8 cm

Step-by-step explanation:

A square and an equilateral triangle have a side in common. If side of triangle is 4/3 cm long. Find the perimeter of figure formed.

Square and equilateral triangle have a side in common

so length of each side is equal

side of a triangle is 4/3 cm long

Perimeter of equilateral Triangle = 3 * sides

= 3 * 4/3 = 4 cm

Perimeter of Square = 4 * side

But one side is common with triangle so effective sides available to calculate perimeter = 4 -1 = 3 sides

Perimeter of square here = 3 * 4/3 = 4 cm

Perimeter of Figure formed = 4 + 4 = 8 cm
