Answer:
AE=22.4
Step-by-step explanation:
BE is 1/2 of BC
BC is 20 cm All sides of a square are equal
BE = 1/2 BC Property of a midpoint.
BE = 10
Now just use Pythagorus
AB^2 + BE^2 = AE^2
AE^2 = 20^2 + 10^2 Perform the sqrs
AE^2 = 400 + 100 Add the terms
AE^2 = 500 Take the square root of both sides
√AE^2 = √500
AE = 22.36
AE ≈ 22.4
Answer:
28 ft
Step-by-step explanation:
Let longer side of rectangle be
and the shorter side be
, thus we can write the ratio:

<em>Now putting 21 into S, we solve for L:</em>

Hence, length of longer side is 28 ft.
