Answer:

length: 32.25 cm
width: 10.75 cm

Step-by-step explanation:

Let w represent the width. Then 3w represents the length. The perimeter formula is ...

P = 2(L +W)

P = 2(3w +w)

86 cm = 8w

w = 10.75 cm

3w = 32.25 cm

The rectangle is 32.25 cm long and 10.75 cm wide.

Solve for x in the diagram below.

bija089 [108]

Answer:

x = 12

Step-by-step explanation:

20° + (6x - 2) = 90°

18° + 6x = 90°

6x = 90° - 18°

6x = 72°

x = 72°/6

x = 12
