Question

What is the length of the diagonal of a rectangle whose width is 90 cm and whose length is 200 cm?

Answer 1

a = 200 cm = 2 m
b = 90 cm = 0,9 m
d = ? (m)

Pythagorean theorem

`a^2+b^2=d^2`

`{d=√(a^2+b^2)=√(2^2+(0.9)^2)=√(4+0.81)=√(4.81)=2.19317 ...(m) \ \approx 219, 32 \ (cm)}`

Answer 2

219.32 cm is the answer
