The length of the rectangle will be equal to 4.5 cm
Step-by-step explanation:
in a rectangle, wide w is 2.8 cm and and length of diagonal is 5.3 cm. To find the length we will use pythagoras theorem, which is given as
+ =
where a = width w, b = length l and c = diagonal d
so we will now have + =
Then we will have
+ =
7.84 + = 28.09
= 28.09 - 7.84
= 20.25
l =
l = 4.5
Therefore, the length of the rectangle is 4.5 cm
