Question

find perimeters of a square of side 2cm and of an equilateral triangle of side 1.5cm. Consruct (a) a line segment whose length is the sum of their perimeters . (b) a line segment whose length is difference of their perimeters.​

Answer 1

Answer:

(a) 12.5 cm & (b) 3.5 cm

Step-by-step explanation:

Perimeter of square of 2 cm = 8cm

Perimeter of an equilateral triangle of 1.5 cm = 4.5

a) line segment length = 8 cm + 4.5cm = 12.5 cm

b) A line segment length is difference = 8cm - 4.5cm = 3.5 cm
