Question

If AB = BC = 7.5cm and CD = 1.5cm then find the length of AC + BD.
​

Answer 1

Step-by-step explanation:

AD =BC = 7.5cm and CD =1.5cm

To Find:

AC+BD = ?

Solution:

Here,

\begin{gathered}AD= AB+BC+CD\\7.5=AB+7.5+1.5\\AB+1.5=0\\AB=(-1.5)\end{gathered}

AD=AB+BC+CD

7.5=AB+7.5+1.5

AB+1.5=0

AB=(−1.5)

Therefore,

\begin{gathered}AC+BD=(AB+BC)+(BC+CD)\\=AB+2BC+CD\\= -1.5 + 2(7.5)+1.5\\=15.0\\\end{gathered}

AC+BD=(AB+BC)+(BC+CD)

=AB+2BC+CD

=−1.5+2(7.5)+1.5

=15.0

Hence, AC+BD = 15AC+BD=15
