A rectangle is 2.8cm wide and the length of each diagonal is 5.3 calculate the length of the rectangle ?

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
