Answer:
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
+
= ![c^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D)
where a = width w, b = length l and c = diagonal d
so we will now have
+
= ![d^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D)
Then we will have
+
= ![5.3^{2}](https://tex.z-dn.net/?f=5.3%5E%7B2%7D)
7.84 +
= 28.09
= 28.09 - 7.84
= 20.25
l = ![\sqrt{20.25}](https://tex.z-dn.net/?f=%5Csqrt%7B20.25%7D)
l = 4.5
Therefore, the length of the rectangle is 4.5 cm
