Answer:
Part a) How are L, W and related?
we know that
in the rectangle of the figure
applying the Pythagoras theorem
d²=W²+L²
the answer part a) is
W²+L²=d²
Part b) If L is 7 units long and W is 5 units long How long is the diagonal to the nearest tenth
d²=W²+L²
W=5 units
L=7 units
so
d²=5²+7²-----> d²=25+49-----> d²=74-----> d=√74----> d=8.6 units
the answer part b) is 8.6 units
