A green cross is formed by placing two rectangles of dimensions 8cm×4cm over

Goshia [24]

Answer:

The perimeter of the green cross is 32 cm

Step-by-step explanation:

Perimeter

It's the sum of all the external side lengths of a given shape.

The green cross formed by two rectangles is shown in the figure below.

We have outlined the dimensions of the external sides of the resulting cross.

Note there are four corners of 2 cm by 2 cm and four sides of 4 cm each.

The total perimeter is:

8 * 2 cm + 4 * 4 cm = 16 cm + 16 cm = 32 cm

The perimeter of the green cross is 32 cm

A cheetah can travel up to 29 meters per second.what is the cheetahs speed to the nearest tenth in miles per hour? (1 mile=1690

Ray Of Light [21]

64.87=64.9 mph
I think I'm not so familiar with meters.
1 mps (meters per second) = about 2.23 mph (miles per hour)
Therefore, 29 x 2.23=64.8712
Rounded to the nearest tenth and it is 64.9.
