Question

ABCD is a rectangle AB =12cm BC=70cm then find AC?

Answer 1

Answer:

The length of AC is 71.02 cm..

Step-by-step explanation:

AB= 12cm

BC = 70cm

Consider Triangle ABC.

We know that each angle of a rectangle measures 90 degree.

Therefore angle B = 90 degree.

By Pythagoras Theorem,

$AC^{2}$ = $AB^{2}$ +$BC^{2}$

$AC^{2}$ = $12^{2}$ + $70^{2}$

$AC^{2}$ =  144 + 4900

$AC^{2}$ = 5044

AC = √5044

AC = 71.02 cm.
