There are 2 rectangles. One was 1.2 cm by 3.4 cm. The other was measured 2.1 cm by 1.7 cm. How much is the perimeter?
ELEN [110]

Answer: See explanation

Step-by-step explanation:

Perimeter of a rectangle is given as:

= 2(length + breadth)

First rectangle measures 1.2 cm by 3.4 cm. The perimeter will be:

= 2(1.2+ 3.4)

= 2(4.6)

= 2 × 4.6

= 9.2cm

Second rectangle measured 2.1 cm by 1.7 cm. The perimeter will be:

= 2(2.1 + 1.7)

= 2 × 3.8

= 7.6cm

Total perimeter = 9.2cm + 7.6cm = 16.8cm
