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?

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

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
