Answer:

75 cm

Step-by-step explanation:

The diagonal d divides the rectangle into 2 right triangles with d as the hypotenuse.

Using the right triangle formed on the left and using Pythagoras' identity.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

d² = 45² + 60² = 2025 + 3600 = 5625 ( take square root of both sides )

d = 75

The diagonal is 75 cm

A parking lot covers 32,420 square feet .what id its area to the nearest thousand feet
Mademuasel [1]

Answer: 32,000

Step-by-step explanation:

the thousands place (1000) is the fourth number to the left of the decimal, so round that one either up or down based on the number just one spot closer to the decimal, in this case, the hundreds place (100).

so we have 32,420

we can ignore the numbers that are going to become zeros as a result of the rounding . .

32,400

let's round 32,XXX either up or down based on the value in the hundreds place. if that value is 5 or greater, than we round up. if it is less than 5, than we round down.

4 is in the hundreds place, so we round down

32,000 is the answer

Hope this helps!!! Good luck!!! ;)
