The length of a rectangle is 9.7 cm more than 4 times the width. if the perimeter of the rectangle is 91.4 cm, what are its dimensions? show your work

width (w): w

Length (L): 4w + 9.7

Perimeter = 2L + 2w

     91.4     = 2(4w + 9.7) + 2(w)

     91.4     = 8w + 19.4 + 2w

     91.4     = 10w + 19.4

      72.0   = 10w

      7.20    = w

Length (L): 4w + 9.7   = 4(7.2) + 9.7   = 28.8 + 9.7   = 38.5

width = 7.2 cm, Length = 38.5 cm

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.

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
