A skyscraper in London, England, has a roof in the shape of a square pyramid. Its approximate dimensions are shown in the net. What is the surface area of the skyscraper's roof, including the base?

Enter your answer in the box.

[ ] m²

3,300 sq meters

Step-by-step explanation:

Base : 30 x 30 = 900

Side Triangle 1 : 40 x 30 / 2 = 600

Side Triangle 2 : 40 x 30 / 2 = 600

Side Triangle 3 : 40 x 30 / 2 = 600

Side Triangle 4 : 40 x 30 / 2 = 600

900 + 600 + 600 + 600 + 600 = 3,330 sq meters

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
